What are the loudest sounds at UB? Where are the university’s quietest spots? What unlikely noises here are around 60 decibels, the level typically associated with a normal conversation between two ...

Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors ...

Sound intensity is referred as the sound power per unit area. It illustrates the flow of acoustic energy produced by a sound source. Not like simple microphones and sound level meters, sound intensity ...

So far we have only considered sound in isolation and we have seen that sound has velocity, frequency, wavelength and reduces in intensity in proportion to the square of the distance from the source.

Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely ...

THE experimental results reported in a previous communication 1 confirm the existence of several maxima for the second- and the third-order diffraction lines at oblique incidence and at low sound ...

This array of piezoelectric sensors is designed to install in theaters and concert halls to harness sound wave energy to create electricity. This miniature proof of concept included 1,042 sensors, and ...

A research team has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does. The findings shattered ...
