In the sound wave, when neighboring air particles are close together; the pressure is higher than atmospheric pressure areas of rarefaction In the sound wave, where neighboring air molecules move apart; the pressure is less than the atmospheric pressure. elasticity and inertia the forces that keep...
A dog while barking delivers about 1 mW of power. If this power is uniformly distributed over a hemispherical area, what is the sound level at a distance of 5 m? What would the sound level be if instead of 1 dog, 5 dogs start barking at the same time each delivering 1 mW of power...

It is possible to enter the industry with an undergraduate degree in music, physics, mathematics, or engineering, followed by a postgraduate in music technology. Sound engineers mostly study engineering, music, or audiovisual communications technologies. Around 53% of sound engineers have a bachelor...

Sound In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. Sonic Of or relating to audible sound A so...
