![]() How Can An Audiologist Measure Tinnitus In Decibels? Even moderately loud sounds can cause hearing damage with too much unprotected exposure, and once sound reaches 140 decibels, it can actually become physically painful. On the other hand, a rock concert can reach ear-piercing levels of over 100 dB SPL, which can cause hearing damage after prolonged exposure. ![]() Normal conversation typically ranges around 60-65 dB SPL, which is safe and comfortable for our ears, and most people watch television at about 70 dB. This is what is measured by an audiometer during a hearing evaluation on an audiogram. dB HL is used to refer to a person’s hearing ability and determines hearing thresholds on a hearing test. Physically, this is the true loudness of a sound and what is measured by a sound level meter for noise readings. dB SPL refers to the magnitude of displacement of molecules in the air. Decibels help quantify sound levels using a logarithmic ratio of one unit of measurement to another, so simply put, it is a way to measure how loud or quiet something is.ĭecibels are typically measured in two ways in relation to hearing: ![]() ![]() You may encounter this unit of measurement in music, electronics, or hearing protection. When it comes to understanding the loudness of sounds – including in the context of tinnitus – we use a unit of measurement called the decibel (abbreviated dB). ![]()
