A weighted decibel scale4/4/2024 ![]() ![]() However, those with more complex symptoms, such as difficulty hearing someone speak even in a quiet environment, should seek guidance from a hearing health provider. People with mild hearing loss might consider over-the-counter (OTC) hearing aids, says Dr. NIOSH also offers a sound level meter app on iOS devices to help people measure their workplace noise exposure. If the volume of any sound causes pain or discomfort, that’s a sign it could be dangerous, which is why it’s important to always have ear plugs or another form of hearing protection on hand. A movie may start at a noise level that feels comfortable, but the soundtrack may become very loud and uncomfortable very fast. Of course, sound levels can change unpredictably in any environment. Wear hearing protection, such as earplugs or earmuffs, if it’s not possible to lower the volume or move away from the loud sound.For example, stand far from speakers at music venues, and keep a safe distance from fireworks during celebrations. Move away from the source of the noise.Lower the volume on personal music devices, such as when listening to car radios or while using headphones.Schurman recommend the following healthy hearing habits to help help prevent noise-induced hearing loss: 110 A-weighted decibels (dBA) and lasts at least two minutesĭr.100 A-weighted decibels (dBA) and lasts at least 14 minutes.85 A-weighted decibels (dBA) and lasts a few hours.Schurman, noise is more likely to damage hearing when it measures: People who are regularly exposed to loud noise in the workplace, such as at a construction site or at concert venues, face an increased risk of hearing loss. ![]() ![]() It’s also important to consider that the impact of loud noise exposure accumulates over time. The louder the sound (which is affected by proximity to the source), the more damage it can cause and the faster damage is likely to occur. The Measurement of SoundĬonsider the volume of a sound, its proximity and your length of exposure when determining how much hearing health damage it may cause, says Dr. Learning more about which decibel levels are safe and which can be harmful can help prevent noise-induced hearing loss and is important to preserving hearing health, says Dr. “A very powerful sound can damage hearing in a short period of time, but many exposures over time to loud sounds also raise the risk of hearing damage.” She advises using hearing protection, whether earplugs or earmuff-type products, on a consistent basis when engaging in noisy activities, such as attending concerts or mowing the lawn. “When we consider whether a noise could be damaging, we think about intensity, but we also think of time,” says Lauren Doolittle, Au.D., a clinical audiologist in Pennsylvania. Noise-induced hearing loss can occur from a single incident, such as firecrackers exploding close to a person’s ear, or it can happen gradually due to repeated exposure to loud sounds over time. ![]() Even small increases in sound intensity can damage a person’s fragile inner ear structures and cause hearing loss, says Dr. Rather, it is logarithmic and better represents how changes in sound intensity feel to our ears, explains Jaclyn Schurman, an audiologist and training officer with the NIDCD. However, unlike other measurement units, the decibel scale isn’t linear. The higher the decibel number, the louder the sound is perceived, says Kelly King, Au.D., an audiologist and program officer with the NIDCD. Decibel Levels And Hearing Health: What To Knowĭecibels (dB) are a measurement unit of sound intensity, also referred to as volume, sound power or sound pressure, according to the National Institute on Deafness and Other Communication Disorders (NIDCD).
