WebApr 5, 2024 · The pressure amplitude for the threshold of hearing is 2 x 10 -5 N/m 2. This is a standard value defined for a pure sine wave at a frequency of 1000 Hz. As we will see later in this class, our ability to hear is a strong function of frequency so the value is quite different at other frequencies. WebCalculate the sound intensity level in decibels for a sound wave traveling in air at 0 ºC and having a pressure amplitude of 0.656 Pa. Strategy We are given Δ p, so we can calculate I using the equation I = ( Δ p) 2 2 ρ v . Using I , we can calculate β straight from its definition in β ( d B) = 10 log 10 ( I I 0) β (dB) = 10 log 10 ( I I 0) .
