Polarization is not produced by sound waves in air. Sound waves are longitudinal waves that do not exhibit polarization, which is a property of transverse waves.
If the same note is played on sitar and flute, the sound produced by them can be distinguished due to the difference in sound quality. Each instrument has a unique timbre or quality of sound caused by the overtones and ...
Women’s voices are thinner (shrill) compared to men’s voices primarily because the frequency is higher. Higher frequency results in a higher pitch, characteristic of women’s voices. This is due to women having shorter and thinner vocal cords that vibrate at ...

The characteristic of sound that determines whether it is thick (grave) or thin (shrill) is pitch. Pitch is related to the frequency of the sound wave, with lower frequencies producing a thick or grave sound and higher frequencies producing a ...
A noise level of 100 decibels corresponds to noise coming from a machine shop. This level of sound is significantly loud and can potentially cause hearing damage with prolonged exposure.
The intensity of sound during normal conversation typically ranges from 50 to 60 decibels. This level is comfortable for human ears and is common in everyday social interactions.
Sound or noise pollution is measured in decibels, a unit that quantifies the intensity of sound. It provides a logarithmic scale to describe sound levels perceived by the human ear.
