Document Summary
I is a periodic soundwave which is power per. 2pv the sound level of a sound wave in decibels is. B tolog 1 reference intensity usually taken to be. I intensity of the sound wave ht longitudinal and travel sand waves are a compressible medium with a speed on the elastic and intertial properties of that medium a bulk. The speed of sound in the gas having modulus b and density p is through that. For sinusoidal sand waves the variation in the position of an element of the median is slx. tl sma. us kx wti the variation in pressure from the equilibrium value is. D mausinlkx wtf is the pressure amplitude the pressure where apna wave is 90 out of the phase with the wave the relationship between sma and dpmax is displacement ma pvwsmax. Ex hearinglinits can detect a human which is called threshold hearing the loudest.
