Muffled hearing, a sense of fullness in ears or a ringing sound after experiencing loud noises can all be signs of temporary threshold shift (TTS). TTS refers to temporary hearing loss after exposure to loud noises. Though the condition is temporary, repeated TTS can be problematic to your hearing health. Continue reading to learn about TTS and how to avoid it.<\/p>\n

Defining Temporary Threshold Shift<\/h2>\n

\"\"<\/p>\n

Hearing loss<\/a> which resolves after hours, days or weeks following noise exposure, is considered a temporary threshold shift. For instance, seeing a loud show at a concert venue can leave you with temporary noise damage.<\/p>\n

TTS can occur from exposure to any type of loud noise. Loud noises can damage the cells and membranes in the cochlea\u2014the hollow bone in the inner ear, and temporarily or permanently damage hearing.<\/p>\n

Threshold shifts are separated into two categories: temporary and permanent. A study on temporary and permanent threshold shifts found that \u201cExposure to intense sound can produce TTS, acute changes in hearing sensitivity that recover over time<\/a>, or PTS, a loss that does not recover to pre-exposure levels. In general, a threshold shift \u226510 dB at 2, 3 and 4 kHz is required for reporting purposes in human studies.\u201d<\/p>\n

While TTS may go away, repeated instances of TTS from loud noise exposure can damage cochlea cells and lead to permanent hearing damage and loss.<\/p>\n

Protecting Against Temporary Threshold Shift<\/h2>\n

To protect against TTS, you want to limit exposure to loud noises and get regular hearing tests<\/a> to track potential hearing loss. A couple of ways to protect against loud noises include:<\/p>\n
