Answer:
The velocity of sound waves is affected by density.
Explanation:
the speed of sound in air is about 343 metres per second (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s. It depends strongly on temperature as well as the medium through which a sound wave is propagating.
Sound pressure: p, SPL,LPA
Sound intensity: I, SIL
