Question: Due to recording mastering and manufacturing limitations, both high and low frequencies were removed from the first recorded signals by various formulae. With low frequencies, the stylus must swing a long way from side to side, requiring the groove to be wide, taking up more space and limiting the playing time of the record. At high frequencies, hiss, pops, and ticks are significant. These problems can be reduced by using equalization to an agreed standard. During recording the amplitude of low frequencies is reduced, thus reducing the groove width required, and the amplitude at high frequencies is increased. The playback equipment boosts bass and cuts treble so as to restore the tonal balance in the original signal; this also reduces the high frequency noise. Thus more music will fit on the record, and noise is reduced.
Try to answer this question if possible: What is done during recordings to help reduce unwanted sounds?
Answer: amplitude of low frequencies is reduced
Question: The Constitution of Bermuda came into force on 1 June 1967; it was amended in 1989 and 2003. The head of government is the premier. A cabinet is nominated by the premier and appointed officially by the governor. The legislative branch consists of a bicameral parliament modelled on the Westminster system. The Senate is the upper house, consisting of 11 members appointed by the governor on the advice of the premier and the leader of the opposition. The House of Assembly, or lower house, has 36 members, elected by the eligible voting populace in secret ballot to represent geographically defined constituencies.

Try to answer this question if possible: With what religious movement do many Puerto Ricans in New Haven associate?

Question: Asthma is thought to be caused by a combination of genetic and environmental factors. Environmental factors include exposure to air pollution and allergens. Other potential triggers include medications such as aspirin and beta blockers. Diagnosis is usually based on the pattern of symptoms, response to therapy over time, and spirometry. Asthma is classified according to the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow rate. It may also be classified as atopic or non-atopic where atopy refers to a predisposition toward developing a type 1 hypersensitivity reaction.
Try to answer this question if possible: What patterns are used to diagnose asthma?
Answer:
the pattern of symptoms, response to therapy over time, and spirometry
