Understanding Sound Pressure Levels and Hearing Damage
The Science Behind Loud Sounds and Hearing Loss
Our ears are sensitive instruments designed to perceive a wide range of sound frequencies. However, prolonged exposure to loud sounds can damage the delicate hair cells within the inner ear, leading to hearing loss. Sound pressure levels (SPLs) measure the intensity of sound, and decibels (dB) are the unit used to quantify SPL.
Normal conversation typically falls between 60-70 dB, while a busy street might reach 80-90 dB. Sounds above 85 dB can start to cause damage to hearing with prolonged exposure. Every 3 dB increase in sound level roughly doubles the amount of sound energy reaching your ears.
