注意，对于给定的信号路径，宽带增益的起始值的选择是任意的，因为在该模型中，频率相关滤波器的传递函数可以被缩放以补充宽带增益值的任何选择。
Note that, for a given signal path, the choice of a starting value for the wide-band gain is arbitrary, since in the model, the transfer function of the frequency-dependent filter may be scaled to complement any choice of wide-band gain value.
图4示出了图2和3的耳机1的功能，并且示出了时间t向右前进的示例信号图。
2 and 3 and shows an example signal diagram with time t progressing rightwards.
在上部，声级L向上对数地增加。
In the upper section, sound level L logarithmically increases upwards.
水平分析器35基于对音频输入信号SI和/或反馈参考信号SR的分析，提供指示耳朵5处的总声级的声级估计LS，将声级估计LS与指示噪声本底水平的预定阈值LT进行比较，并将比较结果SL(如中间部分所示)提供给降噪控制器34。
The level analyzer 35 provides, based on an analysis of the audio input signal SI and/or the feed-backward reference signal SR, a sound level estimate Ls indicating a total sound level at the ear 5, compares the sound level estimate Ls with a predetermined threshold LT indicating a noise floor level and provides the comparison result SL, as illustrated in the middle section, to the noise cancellation controller 34.
降噪控制器34接收比较结果SL，并使用它来控制反馈降噪信号路径37的宽带增益G，如下面部分所示，其中宽带增益G向上对数地增加，以使得宽带增益G在耳朵5处的总声级(由声级估计LS指示)低于噪声本底水平(由预定阈值LT指示)的时间段中与耳朵5处的总声级高于噪声本底水平的时间段相比减小ΔG。
The noise cancellation controller 34 receives the comparison result SL and uses it to control the wide-band gain G of the feed-backward noise cancellation signal path 37, as illustrated in the lower section with wide-band gain G logarithmically increasing upwards, to cause a decrease ΔG of the wide-band gain G in time periods wherein the total sound level at the ear 5 (as indicated by the sound level estimate LS) is below the noise floor level (as indicated by the predetermined threshold LT) compared to time periods wherein the total sound level at the ear 5 is above the noise floor level.
在信号图中，这样的时间段出现在t1和t2之间以及t5之后。
In the signal diagram, such time periods appear between t1 and t2 as well as after t5.
相反地，降噪控制器34使用比较结果SL使得宽带增益G在耳5处的总声级高于噪声本底水平的时间段中与耳5处的总声级低于噪声本底水平的时间段相比增加。
Conversely, the noise cancellation controller 34 uses the comparison result SL to cause an increase of the wide-band gain G in time periods wherein the total sound level at the ear 5 is above the noise floor level compared to time periods wherein the total sound level at the ear 5 is below the noise floor level.
在信号图中，这样的时间段出现在t0和t1之间以及t2和t5之间。
In the signal diagram, such time periods appear between t0 and t1 as well as between t2 and t5.
在时刻t3和t4，预定阈值LT的增大示出了用户对噪声基底的调整，这使得在时刻t5宽带增益G的减小ΔG出现在耳朵5处的总声级比没有这些调整时更高。
At times t3 and t4, increases of the predetermined threshold LT illustrate adjustments of the noise floor by the user which cause the decrease ΔG of the wide-band gain G at time t5 to appear at a higher total sound level at the ear 5 than without those adjustments.
在本文中，耳朵5处的总声级应当理解为由到达耳朵5的声输出信号SO和到达耳朵5的(残余)环境声音SA的组合产生的声级。
In the present context, the total sound level at the ear 5 shall be understood as the sound level arising from the combination of acoustic output signal So arriving at the ear 5 and (residual) ambient sound SA arriving at the ear 5.
在提供声级估计LS时，水平分析器35因此可以使用反馈参考信号SR作为耳朵5处的总声级的估计。
In providing the sound level estimate LS, the level analyzer 35 may thus use the feed-backward reference signal SR as an estimate of the total sound level at the ear 5.
水平分析器35还可以使用音频输入信号SI来细化对耳朵5处的总声级的这种估计，例如以分离声输出信号SO和环境声音SA的贡献，从而能够对将这些声音贡献引导到耳朵5的不同声路径进行单独补偿。
The level analyzer 35 may further refine such an estimate of the total sound level at the ear 5 using the audio input signal SI, e.g. to separate the contributions of the acoustic output signal SO and the ambient sound SA and thus enable individual compensation for the different acoustic paths leading these sound contributions to the ear 5.
水平分析器35还可以使用参考麦克风26的位置和耳朵5的鼓膜之间的估计水平差(例如由于设计或通过使用利用来自多个麦克风的信号获得的水平差的估计)来修改这种声音贡献。
The level analyzer 35 may further modify such sound contributions using estimated level differences between the location of the reference microphone 26 and the tympanic membrane of the ear 5, e.g. by design or by using estimates of level differences obtained using signals from multiple microphones.
注意，由于预定阈值LT与指示耳朵5处的总声级的声级估计LS相比较，所以效果将简单地认为环境声音SA可以不受主动降噪影响到达耳朵5只要环境声音SA和基于音频输入信号SI的音频输出信号SO部分的组合在耳朵5处具有低于噪声本底水平的水平。
Note that since the predetermined threshold LT is compared to the sound level estimate Ls that indicates a total sound level at the ear 5, the effect will, simply put, be that ambient sound SA may arrive at the ear 5 unaffected by the active noise cancellation as long as the combination of the ambient sound SA and the portion of the audio output signal SO that is based on the audio input signal SI has a level at the ear 5 that is below the noise floor level.
相反，当环境声音SA和基于音频输入信号SI的音频输出信号SO部分或其组合在耳朵5处具有高于噪声本底水平的水平时，则环境声音SA将经受主动降噪。
Conversely, when either of the ambient sound SA and the portion of the audio output signal SO that is based on the audio input signal SI, or the combination thereof, has a level at the ear 5 that is above the noise floor level, then the ambient sound SA will be subject to active noise cancellation.
在一些实施例中，降噪控制器34可以提供指示反馈降噪信号路径37的宽带增益G的减小ΔG的增益控制信号SG，并且发射器36可以将增益控制信号SG发送到另一个设备，例如耳麦10的第一耳机1和第二耳机2中相应的另一个。
In some embodiments, the noise cancellation controller 34 may provide a gain control signal SG indicating a decrease ΔG of the wide-band gain G of the feed-backward noise cancellation signal path 37, and the transmitter 36 may transmit the gain control signal SG to another device, such as e.g. a respective other one of the first and second earphones 1, 2 of the headset 10.
在其它实施例中，可以省略发射器36。
In other embodiments, the transmitter 36 may be omitted.
降噪控制器34可以优选地使得宽带增益G的减小ΔG(例如在至少1s、至少5s或至少10s的时间间隔上)平滑地显现，并且使得宽带增益G的增大显现得明显快于宽带增益的减小ΔG(例如在小于200ms、小于100ms、小于50ms或甚至小于20ms的时间间隔内)。
The noise cancellation controller 34 may preferably cause the decrease ΔG of the wide-band gain G to appear smoothly, e.g. over a time interval of at least 1 s, at least 5 s or at least 10 s, and to cause the increase of the wide-band gain G to appear significantly faster than the decrease ΔG of the wide-band gain, e.g. within a time interval of less than 200 ms, less than 100 ms, less than 50 ms or even less than 20 ms.
宽带增益G的平滑减小ΔG可以允许用户仅在音频输入信号SI(可以包括例如来自电话或网络会话中的远程方的音乐或语音)的暂停中听到低水平环境声音SA。
A smooth decrease ΔG of the wide-band gain G may allow the user to hear low-level ambient sound SA only in pauses in the audio input signal SI, which may comprise e.g. music or speech from a remote party in a telephone or network conversation.
这可以降低低水平环境声音SA干扰音频输入信号SI中的这种内容同时降低与用户4感觉到的环境的声学隔离的风险。
This may reduce the risk of low-level ambient sound SA disturbing such content in the audio input signal SI while at the same time reducing the acoustic isolation from the environment felt by the user 4.
另一方面，宽带增益G的快速增加使得能够在环境声音SA变得更响时快速抑制环境声音SA。
A fast increase of the wide-band gain G may, on the other hand, enable quick suppression of ambient sound SA when it gets louder.
水平分析器35优选地执行比较，使得其至少部分地补偿耳朵5的频率依赖性和/或水平依赖性，例如通过至少部分地补偿平均健康人耳的频率依赖性。
The level analyzer 35 preferably performs the comparison such that it at least partly compensates for a frequency dependency and/or level dependency of the ear 5, e.g. by at least partly compensating for the frequency dependency of the average healthy human ear.
水平分析器35例如可以通过在提供声级估计LS时应用公知的等响曲线来执行这种补偿。
The level analyzer 35 may e.g. perform such compensation by applying the well-known equal-loudness contours when providing the sound level estimate LS.
或者，水平分析器35可以使用为当前用户4获得的听觉阈值进行补偿。
Alternatively, the level analyzer 35 may use hearing thresholds obtained for the current user 4 for the compensation.
水平分析器35例如可以在声级估计LS的计算中和/或在比较本身中执行补偿。
The level analyzer 35 may e.g. perform the compensation in the computation of the sound level estimate LS and/or in the comparison itself.
在耳朵5处的总声级低于噪声本底水平的时间段中宽带增益G的减小ΔG可以使得耳机1允许更多的环境声音SA在这样的时间段期间到达耳朵5，同时减小由ANC系统在音频输出信号SO中产生的噪声水平。
The decrease ΔG of the wide-band gain G in time periods wherein the total sound level at the ear 5 is below the noise floor level may cause the earphone 1 to allow more ambient sound SA to arrive at the ear 5 during such time periods while at the same time reducing the level of noise produced by the ANC system in the audio output signal SO.
预定阈值LT可以优选地被设置为指示相对低噪声本底水平，例如在平均健康人类听觉阈值之上0dB到20dB的范围内，例如在100Hz到1kHz的频率范围内，或者在更宽的频率范围内。
The predetermined threshold LT may preferably be set to indicate a relative low noise floor level, such as within a range of 0 dB to 20 dB above the average healthy human hearing threshold, e.g. within a frequency range from 100 Hz to 1 kHz - or within a wider frequency range.
在这种情况下，宽带增益G的减小ΔG可以减小用户4在安静环境中感知到的噪声水平。
In this case, the decrease ΔG of the wide-band gain G may decrease the noise level perceived by the user 4 in quiet environments.
到达耳朵5的环境声音SA的增加可以进一步减少与用户4感觉到的环境的声学隔离。
The increase of ambient sound SA arriving at the ear 5 may further reduce the acoustic isolation from the environment felt by the user 4.
用户输入信号SU可以包括用户4的动作的指示，并且水平分析器35可以优选地基于所指示的动作来调整由预定阈值LT指示的噪声本底水平。
The user input signal SU may comprise an indication of an action of the user 4, and the level analyzer 35 may preferably adjust the noise floor level indicated by the predetermined threshold LT, based on the indicated action.
用户输入信号SU可以例如包括用户4的第一动作的指示，并且水平分析器35可以响应于第一动作的指示来增加所指示的噪声本底水平。
The user input signal SU may e.g. comprise an indication of a first action of the user 4, and the level analyzer 35 may increase the indicated noise floor level in response to the indication of the first action.
相反地，用户输入信号SU可以包括用户4的第二动作的指示，并且水平分析器35可以响应于第二动作的指示来降低所指示的噪声本底水平。
Conversely, the user input signal SU may comprise an indication of a second action of the user 4, and the level analyzer 35 may decrease the indicated noise floor level in response to the indication of the second action.
这可以允许用户4将环境声音SA调节到当耳机处于运行位置时可以到达耳朵5的水平，并且因此可以允许用户4根据个人偏好来平衡降噪和环境感知。
This may allow the user 4 to adjust the level up to which ambient sound SA may arrive at the ear 5 with the earphone in the operating position and may thus allow the user 4 to balance noise cancellation and environment awareness according to personal preference.
在一些实施例中，耳机1可以包括用户接口(未示出)，其检测用户4的操纵并向信号处理器25提供相应的用户输入信号SU。
In some embodiments, the earphone 1 may comprise a user interface (not shown) that detects manipulation by the user 4 and provides a corresponding user input signal SU to the signal processor 25.
在一些实施例中，耳机1和信号处理器25可以利用可以由用户4操纵的用户接口9从外部设备8接收用户输入信号SU。
In some embodiments, the earphone 1 and the signal processor 25 may receive a user input signal SU from an external device 8 with a user interface 9 that can be manipulated by the user 4.
降噪控制器34可以通过修改包括在反馈降噪信号路径37中并与反馈降噪滤波器32串联布置的放大器(未示出)的增益来控制反馈降噪信号路径37的宽带增益G。
The noise cancellation controller 34 may control the wide-band gain G of the feed-backward noise cancellation signal path 37 by modifying the gain of an amplifier (not shown) comprised by the feed-backward noise cancellation signal path 37 and arranged in series with the feed-backward noise cancellation filter 32.
因此，当比较结果SL指示耳朵5处的总声级高于噪声本底水平时，降噪控制器34可以将放大器的增益设置为等于第一增益值，并且当比较结果SL指示耳朵5处的总声级低于噪声本底水平时，降噪控制器34可以将放大器的增益设置为等于第二增益值，其中第二增益值等于由低于1(unity)的放大器缩放因子缩放的第一增益值。
The noise cancellation controller 34 may thus set the gain of the amplifier equal to a first gain value when the comparison result SL indicates that the total sound level at the ear 5 is above the noise floor level and set it equal to a second gain value when the comparison result SL indicates that the total sound level at the ear 5 is below the noise floor level, wherein the second gain value equals the first gain value scaled by an amplifier scaling factor below unity.
在这种情况下，宽带增益G的减小ΔG等于放大器缩放因子的乘法逆。
In this case, the decrease ΔG of the wide-band gain G equals the multiplicative inverse of the amplifier scaling factor.
图5示出了图2的耳机1的耳机的反馈降噪滤波器32的反馈传递函数H的示例传递函数，其中滤波器增益GF向上对数增加，信号频率f向右增加。
FIG. 5 shows example transfer functions of the feed-backward transfer function H of the feed-backward noise cancellation filter 32 of an earphone of the earphone 1 of FIG. 2 with filter gain GF logarithmically increasing upwards and signal frequency f increasing rightwards.

无取向电工钢板作为在轧制板上的所有方向上磁特性均匀的钢板，广泛应用于发电机的铁芯、电动机、小型变压器等。
A non-oriented electrical steel sheet is a steel sheet of which a magnetic property thereof is uniform in all directions on a rolling plate, and has been widely used in a motor, and as an iron core of an electric generator, an electric motor, a small transformer, and the like.
电工钢板可分为以下两种形式：为了改善冲压工艺后的磁特性需进行消除应力退火(SRA)；以及当热处理导致的成本损失大于消除应力退火引起的磁特性效果时，省略消除应力退火。
The electrical steel sheet can be classified into two types such as one in which stress relief annealing (SRA) for improving the magnetic property after punching work should be practiced and another in which the SRA is omitted when cost loss is larger than the effect of the magnetic property by the SRA.
绝缘覆膜作为在马达、发电机的铁芯、电动机、小型变压器等产品的收尾加工制造工序中涂覆的覆膜，通常对其要求抑制涡电流产生的电学特性。
An insulating film is a film coated in a finishing process for manufacturing a product such as a motor, a generator iron core, an electric motor, a small-sized transformer, and the like, and requires an electrical characteristic that suppresses occurrence of an eddy current.
除此此外，还要求连续冲压加工性、耐粘着性和表面密接性。
In addition, continuous punching workability, stickiness resistance, and surface close contacting properties are required.
连续冲压加工性是指，以规定形状冲压加工后对多个进行层压以制成铁芯时，抑制模具磨损的能力。
The continuous punching workability means the ability of suppressing abrasion of a mold when preparing iron cores by laminating many materials after the punching work in a predetermined shape.
耐粘着性是指，在消除钢板的加工应力而恢复磁特性的消除应力退火过程之后，铁芯钢板间不密接的能力。
The stickiness resistance means the ability to not stick between steel cores after a stress relief annealing process that restores the magnetic characteristic by removing the processing stress of the steel sheet.
除了这些基本特性以外，还要求涂覆溶液的优异的涂覆作业性和配合之后可长时间使用的溶液稳定性等。
In addition to the basic characteristics, excellent application workability of a coating solution, solution stability usable for a long period after the combination, and the like, are also required.
这种绝缘覆膜只有使用焊接、夹紧(clamping)、紧扣(interlocking)等等额外的接合方法才能够制造成电工钢板产品。
Such an insulating film can be manufactured as an electrical steel sheet product by only using separate fastening methods such as welding, clamping, and interlocking.

Meanwhile, there have been attempts to fasten by thermal welding of an adhesive solution applied to an electrical steel sheet surface without using conventional fastening methods such as welding, clamping, interlocking, and the like.
出于这种目的开发的粘合涂覆的主要成分由有机物组成。
A main component of adhesive coating developed for this purpose is formed of organic materials.
然而，有机类粘合涂覆组合物在消除应力退火工序时，有机物在高温下被分解，不仅表面特性(绝缘、密接、耐腐蚀等)会劣化，各电工钢板单张之间的粘合力(接合力)也会几乎消失。
However, since the organic adhesive coating composition undergoes a stress relief annealing process, the organic material decomposes at a high temperature and thus the surface characteristic (insulation, adhesion, corrosion resistance, and the like) is deteriorated and the adherence (fastening force) between each electrical steel sheet is almost lost.
此外，由热可塑性树脂与低熔点无机成分组成的绝缘膜组合物已被悉知。
In addition, an existing insulating coating film composition formed of a thermoplastic resin and a low melting point inorganic component is known.
作为低熔点无机成分，例举了低熔点玻璃原料、液态玻璃或者它们的硅溶胶。
As a low melting point inorganic component, a low melting point glass frit, water glass, or colloidal silica is exemplified.
然而，低熔点玻璃原料和液态玻璃不仅与热可塑性树脂的相溶性差，而且存在在消除应力退火处理工艺之后，由于树脂被分解导致粘结力急速下降的问题。
However, the low-melting point glass frit and water glass not only have poor compatibility with thermoplastic resins, but also have a problem in that the bonding force is rapidly deteriorated due to decomposition of the resin after the stress relief annealing treatment process.
