WebFeb 28, 2016 · If you change only the frequency of a source (constant amplitude), you most definitely change the intensity of the wave, so the level will change. Plus, you are confusing loudness (a psychoacoustic perception) … WebIf L p is the sound pressure level and L i is the sound intensity, then: L p = 20 log 10 ( p r m s p r e f) = 10 log 10 ( p r m s 2 p r e f 2) The intensity of the sound wave, however, is proportional to the square of the sound pressure, or I ∝ p r m s 2. This gives: L p = 10 log 10 ( p r m s 2 p r e f 2) dB = 10 log 10 ( I r m s I r e f) dB = L i

WebThus, an increase in absolute intensity from 10-12 to 10-11 watt per square metre corresponds to an increase of 10 decibels, as does an increase from 10-1 to 1 watt per square metre. The correlation between the absolute intensity of a sound wave and its decibel level is shown in Table 1, along with WebThe scale for measuring intensity is the decibel scale.
