In physics, sound is a vibration that typically propagates as an audible wave of pressure, 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. Humans can only hear sound waves as distinct pitches when the frequency lies between about 20 Hz and 20 kHz. Sound above 20 kHz is known as ultrasound and has different physical properties from sound below 20 kHz. Sound waves below 20 Hz are called infrasound. Different species have different hearing ranges. In terms of frequency, the range of ultrasound, infrasound and other upper limits is called the ultrasound.
In physics, a traveling wave is a wave that propogates without a constant shape, but rather one that changes shape as it moves. In other words, its shape changes as a function of time.

Oh, the pressure amplitude pressure amplitude p is proportional to the amplitude off displacement and ah, frequency. So the pressure amplitude off one sound Where is higher by effect? Toral. Full 24 and six. So this is higher by 2.6. Because off the pressure amplitude proposal toe the displacement amplitude in body be, uh we are asked to find the ratio's off the intensities. So the intensity cross warning to 2.6 off F to the intensity off F that is equal to, um, because the intensities are proportional to their frequency square. So the just across morning do there the higher value, which is a 2.6 F. Then this will equal to 2.6 F Square or F square. Well, this will give us approximately value off 6.86 point eight. End off the problem. Thank you. Forward
