WebA sound that is 10*10*10*10 or 10000 times more intense (1*10 -8 W/m 2) is assigned a sound level of 40 db. Observe that this scale is based on powers of 10. If one sound is … WebJul 10, 2024 · The greater the relative speed is, the greater the effect. Doppler Effect The Doppler effect occurs not only for sound but for any wave when there is relative motion between the observer and the source. There are Doppler shifts in the frequency of sound, light, and water waves, for example. WebThe more intense sound is produced by a source that has larger-amplitude oscillations and has greater pressure maxima and minima. Because pressures are higher in the greater-intensity sound, it can exert larger forces on the objects it encounters. The Decibel Scale oversized lift chairs
