Sound is a kind of energy that is made by vibrating materials. The waves of sound are created when the vibrating body generates the medium around it to vibrate. Wave movement is often referred to as propagation in the physical world. Propagation medium requires the medium to be elastic, ...
The pitch of a sound is directly related to the frequency of the vibrations of its waves. People with excellent hearing can hear very low sounds, vibrating about 20 times per second, all the way up to high pitches with frequencies of 20,000 vibrations per second. Other animals can hear ...
METHOD AND DEVICE FOR REDUCING VIBRATION OF A VIBRATING BODY AND SOUND GENERATED BY VIBRATIONPURPOSE:To suppress the vibration and to reduce its noise by analyzing the frequency of the vibration in real time and adjusting the expansion and contraction of the vibration body with its real-time ...
a periodic disturbance in the pressure or density of a fluid or in the elastic strain of a solid, produced by a vibrating object. It has a velocity in air at sea level at 0°C of 331 metres per second (741 miles per hour) and travels as longitudinal waves (as modifier): a sound ...
Musical sound, any tone with characteristics such as controlled pitch and timbre. The sounds are produced by instruments in which the periodic vibrations can be controlled by the performer. From a bell ringing to a door slamming, any sound is a potential

vibrating when other calling males were in proximity. Males exert more effort for wing vibration and stridulation when they are in groups and this increased wingbeat results in higher fundamental frequencies of the produced sound. In addition, we should not exclude the possibility that this ...
