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...
The smart amplifier helps to deliver clearer audio by boosting volume across the entire audio spectrum, not just at certain frequencies. This ensures crystal-clear highs and powerful bass for a superlative audio experience. An octave spectrum line chart with volume in decibels on the X axis, and...

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 ...
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...

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 ...
The beats are formed when two sound waves have the value of the same amplitude but different frequencies interacting with one another. The resultant wave of two sound waves consists of periodic decrease and increase in the sound amplitude, which is known as beats. The resultant frequency of the...
