The cells can remain this way for several days or even weeks, which is why it takes some time to regain your full sense of hearing. The louder the noise, the longer it will take to recover.<\/p>\n<h2>How Loud Is Too Loud?<\/h2>\n<p>Sounds over 85 dB can cause TTS or permanent damage to the hearing system. For reference, below is a list put together by the <a href=\"https:\/\/www.nidcd.nih.gov\/health\/noise-induced-hearing-loss\">National Institute on Deafness and Other Communication Disorders<\/a> of the average decibel rating of familiar sounds:<\/p>\n<ul>\n<li>Normal conversation: 60-70 dB.<\/li>\n<li>Movie theater: 74-104 dB.<\/li>\n<li>Motorcycles: 80-110 dB.<\/li>\n<li>Sporting events and concerts: 94-110 dB.<\/li>\n<li>Sirens: 110-129 dB.<\/li>\n<li>Fireworks show: 140-160 dB.<\/li>\n<\/ul>\n<h2>Temporary Threshold Shift Can Be Serious<\/h2>\n<p>As the name suggests, TTS is temporary, but that doesn\u2019t mean it isn\u2019t serious.<\/p>\n<p>A single loud concert probably won\u2019t cause any permanent damage to your hearing system; however, repeated exposure can. <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4988324\/\">Repeated episodes of TTS can become permanent threshold shift (PTS)<\/a>.<\/p>\n<p>In most cases, it\u2019s the high-frequency sounds like consonants that are most affected.<\/p>\n<h2>Preventing Temporary Threshold Shift<\/h2>\n<p>In order to <a href=\"https:\/\/hearingsystemsinc.com\/hearing-loss\/hearing-protection\/\">prevent<\/a> TTS and PTS, you should wear earplugs whenever you\u2019re exposed to sounds over 85 dB.<\/p>\n<p>For more information about TTS or to <a href=\"https:\/\/hearingsystemsinc.com\/contact\/\">schedule an appointment<\/a> with a hearing expert, call Hearing Systems today.<\/p>\n<ul class=\"related-posts\">\n<li><a href=\"https:\/\/hearingsystemsinc.com\/why-hearing-checks-should-be-a-regular-part-of-your-hearing-routine\/\" class=\"related-post\">Why Hearing Checks Should Be a Regular Part of Your Hearing Routine<\/a><\/li>\n<li><a href=\"https:\/\/hearingsystemsinc.com\/how-to-support-your-partner-with-hearing-loss-this-valentines-day\/\" class=\"related-post\">How To Support Your Partner With Hearing Loss This Valentine\u2019s Day<\/a><\/li>\n<li><a href=\"https:\/\/hearingsystemsinc.com\/understanding-shingles-and-its-impact-on-hearing\/\" class=\"related-post\">Understanding Shingles and Its Impact on Hearing<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>You know that feeling of muffled hearing after attending a concert at White Oak Music Hall or walking by a noisy construction site?
