Birds in cities are damaging their health by trying to sing above the noise of urban life. New research shows that male birds are trying to compete against traffic and city sounds. They are now singing louder and at higher frequencies, which could harm their vocal cords. Some birds are ...
Sound is energy in the form of vibrations or oscillations. Noise is a term we use to describe unwanted sounds.
(1)词义猜测题。根据前文Basically,your brain increases sounds in the higher pitch frequencies,making them sound louder than they actually are.(基本上,你的大脑增加了更高音调频率的声音,使它们听起来比实际更响。)可知此处意为最高音可能会屏蔽掉低音。所

Frequency determines the pitch, with higher frequencies producing higher pitch notes and lower frequencies producing lower pitch notes. The brain is able to interpret these characteristics of sound, but before that can happen, the sound waves must be detected by a sense organ. That, of course, ...
This simulates the fact that we tend to be more sensitive to high frequencies and less sensitive to low ones in our perception of loudness. After this K-weighting filter is applied to the audio, its R.M.S. level is calculated and the resulting values are used for the first three of ...
We thus ran acoustic analysis in 12 consecutive windows to obtain fundamental frequencies and root mean square (RMS) values for each stimulus, in order to remain as close as possible to the pitch and loudness that were actually heard by the participants. The impact of segment and task were ...
whereas IEMs come withvarious types of drivers. You see, dynamic drivers tend to handle lower frequencies (bass and sub-bass) well but not higher frequencies (treble). In earbuds, dynamic drivers are forced to handle all the frequencies (lows, mids, and highs) on their own, which is not...
