尽管这些差异可能对实现提出不同的挑战，但是本申请的教导可以应用于降噪耳机类型以及其组合。
Even though these differences may present different challenges for the implementation, the teachings of the present application may be applied to both noise cancellation earphone types as well as to combinations hereof.
在上述耳机1的一些实施例中，具有反馈麦克风26和反馈降噪滤波器32的反馈降噪信号路径37因此可以被包括前馈麦克风26和前馈降噪滤波器32的前馈降噪信号路径37代替，其中前馈麦克风26被布置成主要拾取环境声音SA，以根据拾取的信号提供前馈参考信号SR，并且其中前馈降噪滤波器32将前馈传递函数H应用于前馈参考信号SR，以提供前馈降噪信号SC。
In some embodiments of the earphone 1 described above, the feed-backward noise cancellation signal path 37 with the feed-backward microphone 26 and the feed-backward noise cancellation filter 32 may thus be replaced with a feed-forward noise cancellation signal path 37 comprising a feed-forward microphone 26 and a feed-forward noise cancellation filter 32, wherein the feed-forward microphone 26 is arranged to primarily pick up ambient sound SA to provide a feed-forward reference signal SR in dependence on the picked-up signals and wherein the feed-forward noise cancellation filter 32 applies a feed-forward transfer function H to the feed-forward reference signal SR to provide a feed-forward noise cancellation signal SC.
相应地，输出单元33可以通过组合音频输入信号SI和前馈降噪信号SC来向电声换能器23提供音频输出信号SD，并且信号处理器25可以从外部设备8接收音频输入信号SI和用户输入信号SU以及前馈参考信号SR，处理这些信号并将得到的音频输出信号SD提供给电声换能器23。
Correspondingly, the output unit 33 may provide the audio output signal SD to the electroacoustic transducer 23 by combining the audio input signal SI and the feed-forward noise cancellation signal Sc, and the signal processor 25 may receive the audio input signal SI and the user input signal Su from an external device 8 as well as the feed-forward reference signal SR, process these signals and provide the resulting audio output signal SD to the electroacoustic transducer 23.
此外，降噪控制器34可以自适应地控制前馈传递函数H，以使得声输出信号SO抵消环境声音SA，使得当耳机1处于运行位置时，到达耳朵5的环境声音SA的水平降低，同时仍然允许期望的声音(例如在音频输入信号SI中接收的音乐或语音)通过。
Furthermore, the noise cancellation controller 34 may adaptively control the feed-forward transfer function H to cause the acoustic output signal So to counteract ambient sound SA, such that, with the earphone 1 in the operating position, the level of ambient sound SA arriving at the ear 5 is reduced while still allowing desired sound, such as music or speech received in the audio input signal SI, to pass through.
前馈麦克风26由此可以用作耳机1的前馈降噪系统的参考麦克风。
The feed-forward microphone 26 may thereby function as reference microphone for the for the feed-forward noise cancellation system of the earphone 1.
在上述耳机1的一些实施例中，具有反馈麦克风26和反馈降噪滤波器32的反馈降噪信号路径37可以由包括前馈麦克风和前馈降噪滤波器的前馈降噪信号路径(未示出)来补充，其中前馈麦克风被布置成主要拾取环境声音SA以根据拾取信号提供前馈参考信号，并且其中前馈降噪滤波器将前馈传递函数应用于前馈参考信号以提供前馈降噪信号。
In some embodiments of the earphone 1 described above, the feed-backward noise cancellation signal path 37 with the feed-backward microphone 26 and the feed-backward noise cancellation filter 32 may be complemented by a feed-forward noise cancellation signal path (not shown) comprising a feed-forward microphone and a feed-forward noise cancellation filter, wherein the feed-forward microphone is arranged to primarily pick up ambient sound SA to provide a feed-forward reference signal in dependence on the picked-up signals and wherein the feed-forward noise cancellation filter applies a feed-forward transfer function to the feed-forward reference signal to provide a feed-forward noise cancellation signal.
相应地，输出单元33可以通过组合音频输入信号SI、反馈降噪信号SC和前馈降噪信号来向电声换能器23提供音频输出信号SD，并且信号处理器25可以接收来自外部设备8的音频输入信号SI和用户输入信号SU以及反馈参考信号SR和前馈参考信号，处理这些信号，并将得到的音频输出信号SD提供给电声换能器23。
Correspondingly, the output unit 33 may provide the audio output signal SD to the electroacoustic transducer 23 by combining the audio input signal SI, the feed-backward noise cancellation signal SC and the feed-forward noise cancellation signal, and the signal processor 25 may receive the audio input signal SI and the user input signal Su from an external device 8 as well as the feed-backward reference signal SR and the feed-forward reference signal, process these signals and provide the resulting audio output signal SD to the electroacoustic transducer 23.
此外，降噪控制器34可以自适应地控制反馈传递函数H和前馈传递函数，以使得声输出信号SO抵消环境声音SA，使得当耳机1处于运行位置时，到达耳朵5的环境声音SA的水平降低，同时仍然允许期望的声音(例如在音频输入信号SI中接收的音乐或语音)通过。
Furthermore, the noise cancellation controller 34 may adaptively control feed-backward transfer function H and the feed-forward transfer function to cause the acoustic output signal So to counteract ambient sound SA, such that, with the earphone 1 in the operating position, the level of ambient sound SA arriving at the ear 5 is reduced while still allowing desired sound, such as music or speech received in the audio input signal Si, to pass through.
虽然反馈麦克风26用作耳机1的降噪系统的反馈部分的参考麦克风，但是前馈麦克风因此可以用作耳机1的降噪系统的前馈部分的参考麦克风。
While the feed-backward microphone 26 functions as reference microphone for the feed-backward portion of the noise cancellation system of the earphone 1, the feed-forward microphone may thus function as reference microphone for the for the feed-forward portion of the noise cancellation system of the earphone 1.
在包括前馈降噪信号路径37的耳机1的实施例中，降噪控制器34可以适于以与上述用于控制反馈降噪信号路径37的宽带增益G相同的方式来控制前馈降噪信号路径37的宽带增益G-特别地引起前馈降噪信号路径37的宽带增益G在其中耳朵5处的总声级低于噪声本底水平的时间段中与其中耳朵5处的总声级高于噪声本底水平的时间段相比减小ΔG。
In embodiments of the earphone 1 comprising a feed-forward noise cancellation signal path 37, the noise cancellation controller 34 may be adapted to control the wide-band gain G of the feed-forward noise cancellation signal path 37 in the same way as described above for controlling the wide-band gain G of the feed-backward noise cancellation signal path 37 - in particular to cause a decrease ΔG of the wide-band gain G of the feed-forward noise cancellation signal path 37 in time periods wherein the total sound level at the ear 5 is below the noise floor level compared to time periods wherein the total sound level at the ear 5 is above the noise floor level.
在包括前馈降噪信号路径37的耳机1的实施例中，水平分析器35可以基于对音频输入信号SI和音频输出信号SO中的至少一个以及前馈参考信号SR和前馈降噪信号SC中的至少一个的分析来提供声级估计LS，以便估计声输出信号SO和环境声音SA的组合影响。

类似地，在包括反馈降噪信号路径37和前馈降噪信号路径的耳机1的实施例中，降噪控制器34可以适于以上述方式控制反馈降噪信号路径37的宽带增益G和前馈降噪信号路径的宽带增益中的一个或两个。
Similarly, in embodiments of the earphone 1 comprising both a feed-backward noise cancellation signal path 37 and a feed-forward noise cancellation signal path, the noise cancellation controller 34 may be adapted to control either or both of the wide-band gain G of the feed-backward noise cancellation signal path 37 and the wide-band gain of the feed-forward noise cancellation signal path in the way described above.

In some embodiments, the noise cancellation controller 34 may provide the gain control signal SG to indicate either or both of a decrease ΔG of the wide-band gain G of the feed-backward noise cancellation signal path 37 and a decrease of the wide-band gain of the feed-forward noise cancellation signal path.

In some binaural embodiments of the headset 10, the first earphone 1 may comprise an earphone according to any of the embodiments of an earphone 1 described above, however comprising the transmitter 36 that transmits the gain control signal SG provided by the noise cancellation controller 34.
在耳麦10的这种实施例中，第二耳机2可以包括根据上述耳机1的任何实施例的耳机，但是被修改为从第一耳机1接收增益控制信号SG。
In such embodiments of the headset 10, the second earphone 2 may comprise an earphone according to any of the embodiments of an earphone 1 described above, however modified to receive the gain control signal SG from the first earphone 1.
然而，在第二耳机2的这种实施例中，上述功能块中的一些可以被省略和/或具有减少或改变的功能。
In such embodiments of the second earphone 2, some of the above described functional blocks may, however, be omitted and/or have reduced or changed functionality.
因此，第二耳机2至少包括外壳21、悬挂在挡板24中的电声换能器23、信号处理器25和参考麦克风26。

在第二耳机2的信号处理器25中，可以省略音频输入信号SI的接收。

因此，第二耳机2的输入单元31可以从第一耳机1接收增益控制信号SG，并且可选地，从例如第一耳机1或从外部设备8接收另外的音频输入信号SI。
The input unit 31 of the second earphone 2 may thus receive the gain control signal SG from the first earphone 1 and optionally, a further audio input signal SI., e.g. from the first earphone 1 or from an external device 8.

The noise cancellation controller 34 of the second earphone 2 adaptively controls the further transfer function H to cause the further acoustic output signal So to counteract ambient sound SA, such that, with the second earphone 2 in the operating position, the level of ambient sound SA arriving at the ear 6 is reduced, while optionally still allowing desired sound, such as music or speech received in the audio input signal Si, to pass through, and further controls the wide-band gain G of the noise cancellation signal path 37 of the second earphone 2 in dependence on the gain control signal SG received from the first earphone 1 to cause a decrease ΔG of the wide-band gain G of the noise cancellation signal path 37 of the second earphone 2 that is synchronized with the decrease ΔG of the wide-band gain G of the noise cancellation signal path 37 of the first earphone 1.
因此，在第二耳机2的信号处理器25中，可以省略水平分析器35。
In the signal processor 25 of the second earphone 2, the level analyzer 35 may thus be omitted.

Some embodiments may have less than six sided structures, including three sided structures or five sided structures, or structures that have even less sides, provided again that the structures are aligned in rows along a first direction but staggered along the perpendicular second direction.
三维结构10，特别是当设计成六边的多边形结构时，可允许毡片1具有改善的增强特性。
The three-dimensional structures 10, particularly when designed as six-sided polygonal structures, may allow for improved reinforcement characteristics of the mat 1.
作为实例，结构10的成型可允许在构成每个三维结构10的长丝和相邻结构的长丝中的粘合点得以强化，以便有助于防止毡片1在载荷下自身塌陷。
As an example, the shaping of the structures 10 may allow for the strengthened bond points in the filaments comprising each three-dimensional structure 10 and adjacent ones of the structures, so as to aid in prevention of the mat 1 from collapsing into itself when under load.

在相邻结构之间也可以没有聚合物长丝，并且因此，空间20可完全没有附加材料。
There also may be no polymeric filaments between adjacent structures, and thus, the space 20 may be entirely free of additional material.
在这种情况下，将结构粘合到织物上(这将在下文更详细地描述)允许以连续的方式提供毡片。
In such a case, the bonding of the structures to a fabric, described in more detail below, allows for the mat to be provided in a continuous manner.

The indentation may protrude at least part way, or even fully through the thickness of the three-dimensional structure 10.
即，压痕可从毡片的上表面朝毡片1的下表面至少部分地突出，并且在一些情况下可一直突出到毡片的下表面。
That is, the indentation may protrude from the upper face of the mat at least part way toward the lower face of the mat 1, and in some cases may protrude all the way to the lower face of the mat.
压痕可以以与结构之间的间隔相同的方式形成，并且可使用模具形成。
The indentation may be formed in the same manner as the spacing between the structures, and may be formed using a mold.
压痕也可通过使用模具的压熔来形成。
The indentation may also be formed by press melting using the mold.
毡片1的厚度(例如，从毡片的最下表面到三维结构10的最上表面)可为约1-约20mm，或约3-约10mm，或约3mm，约6mm或约10mm。

The mat may be structured to advantageously allow for installation in any orientation, and may have drainage ability along the machine direction of the drainage component, the cross (perpendicular) direction thereto, and even along one or more diagonal or slanted directions.

The three-dimensional structures 10 and, ultimately, the mat 1 may be formed by extrusion of the thermoplastic material at a temperature above the melting point of the material into a structure or mold having a patterned configuration.
该模具可具有与最终制得的毡片相同或基本上类似的图案化构造。
Such a mold may have the same or substantially similar patterned configuration as the ultimately produced mat.
例如，一种用于制备毡片的预期工艺是利用一种方法，其中将连续熔纺热塑性单丝挤出到异型支撑结构或模具上，形成不规则环的重叠行，其在随机的交叉点自粘合或熔合，而不使用任何粘合剂或增强插入物。
By way of example, a contemplated process for producing the mat is to utilize a method where continuous melt-spun thermoplastic monofilaments are extruded onto a profiled support structure or mold in overlapping rows of irregular loops which are self-bonded or fused at random points of intersection without using any bonding agent or reinforcing inserts.
然而，也可使用粘合剂或插入物。

Referring back to FIG. 1, in some embodiments, the mat 1 can optionally include a fabric attached thereto 2.
该织物可为任何可行的织物，或者被认为是羊毛或无纺布，并且也可为本领域中被理解为构成雨棚(weather barrier)的任何组件，例如由DuPont公司生产的 织物2可具有保护毡片1免于接受不希望量的湿气和/或材料如灰泥或砂浆的质量，并且可用作抓层(grablayer)以帮助在墙壁结构内将复合组件连接在一起。
The fabric 2 may have a quality to protect the mat 1 from receiving unwanted amounts of moisture and/or material such as stucco or mortar, and may act as a grab layer to help connect the composite components together within the wall structure.
在一些实施方案中，织物2为过滤织物。
