For a sound wave in air of frequency 3500 Hz and average intensity 1 W/m² (pain threshold)what is the maximum change in pressure (pressure amplitude)of the wave?

Question

Quizplus · Accepted Answer

The pressure amplitude can be calculated using the formula: ΔP = √(2 * ρ * v * I), where ρ is the density of air (approximately 1.21 kg/m³), v is the speed of sound in air (approximately 343 m/s), and I is the intensity. Substituting the values, we get ΔP ≈ 28.6 N/m².
