Question

An online tune generator creates sine sound waves in the air with a displacement amplitude of 0.04 mm at f₁ = 200 Hz and f₂ = 20 kHz. What is the pressure amplitude (p_max) at each frequency? Specify, under these conditions, if these sound frequencies are harmful to human hearing. The pressure variation that corresponds to the harm threshold is 30 Pa.

Accepted Answer

At f₁ p_max = 2.08 × 10¹ Pa; It is not harmful to human hearing
At f₁ p_max =2.08 × 10³ Pa; It is harmful to human hearing

Answer

At f₁ p_max = 1.04 × 10¹ Pa; It is not harmful to human hearing
At f₁ p_max = 1.04 × 10³ Pa; It is harmful to human hearing

Answer

At f₁ p_max = 1.04 × 10¹ Pa; It is harmful to human hearing
At f₁ p_max = 1.04 × 10³ Pa; It is not harmful to human hearing

Answer

At f₁ p_max = 2.08 × 10¹ Pa; It is harmful to human hearing
At f₁ p_max = 2.08 × 10³ Pa; It is not harmful to human hearing
