Web14 apr. 2024 · The intensity of sound is measured in decibels (dB), and exposure to sounds at or above 85 dB can cause hearing damage if exposure is prolonged or repeated. For example, a rock concert or music played through headphones at a high volume can reach levels of 100 dB or more, which can cause damage to the hair cells in the inner ear. WebThe spectral distribution of noise can vary with frequency, so its power density is measured in watts per hertz (W/Hz). Since the power in a resistive element is proportional to the square of the voltage across it, noise voltage (density) can be described by taking the square root of the noise power density, resulting in volts per root hertz ( ).
