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(声带).Some birds are choosing to sing at night instead of during the day.This makes them more open to attack and...
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 ...
That said, it has two factors that set it apart. First, it’s measuring the K-weighted, filtered audio—as previously described. This means that it’s less sensitive to very low frequencies and slightly more sensitive to high ones. This solves two problems that notoriously plagued standard R...
a. The pitch will get higher. b. The pitch will get lower. c. The sound will get louder. d. The sound will get quieter. The shortest wavelengths of visible light are sensed as red, while the longest wavelengths of light are sensed as purple. Indicate whether the statement ...
1) The two year old girl is able to hear the sound. 2) Children can hear sound of somewhat higher frequencies upto 30 kHz.
As a result, whales are trying to adapt either by making much louder noises or by calling at higher frequencies."Whales are well known for their ability to communicate using low-frequency noises. Sound waves in the oceans are hardly deadened (减弱) at all by the water and so larger ...

Smaller speakers, for instance, often excel in producing higher frequencies with more clarity. So, if you’re into music with detailed vocal and instrument lines, sizes like 4-inch, 3.5-inch might be your thing. Conversely, bigger units like 6.9 or 6.5-inch speakers tend to respond better ...
Dirac Distortion Control Smartphone speakers aren't very capable of playing louder content due to audio crackling and distortion at higher volumes. This is especially apparent when higher pitched frequencies are playing from certain instruments like pianos. This phenomenon is known as "piano distortion,...
Researchers used recording equipment which could pick up frequencies between 20 and 250 kilohertz, reaching more than 15 times higher than the frequency an adult can hear. In the greenhouse setting, they also recorded a group of tomato and tobacco plants as they grew increasingly dehydrated(脱水的...
