FAQs from – part 6

Over the next months, I will be uploading some commonly viewed FAQs from  This is the website of the Musicians’ Clinics of Canada, and was completely updated over the last Christmas holidays.  I should have entitled it “What I did over the Christmas holidays”!  A full range of FAQs will eventually cover pretty much everything we know about music and the prevention of hearing loss.

Feel free to submit other questions that can be answered in 4-5 sentences and I may include them in future posts…

I went to a concert last night and my ears are still ringing. Will this stop?

The ringing is called tinnitus. Actually, tinnitus refers to any noises that are heard in the head, that don’t come from the outside. Tinnitus comes in two flavours- objective and subjective. Objective tinnitus is tinnitus that can be heard by other people. This is very rare, and is usually related to blood vessel problems in the ear. Subjective tinnitus is much more common and refers to the type of tinnitus that only the person can hear. But, to answer your question. You are probably suffering from TTS from the concert.

Well, … thank you for that, but what is TTS?

What a good question! TTS stands for Temporary Threshold Shift. This is a fancy way of saying temporary hearing loss. After a loud concert, or a day in the factory, your hearing is temporarily reduced. After about 16 hours to 18 hours, this resolves and your hearing should return to the level it was before (hopefully normal). When the hearing is reduced, there is frequently tinnitus, which is especially noticed in quiet places such as when you are trying to sleep. The tinnitus and hearing loss (sometimes felt as a numbness in your ears) should completely resolve after 16 hours. BUT, it turns out that TTS may not be just a benign characteristic of too much noise or music. Recent research indicates that while the hearing loss (as measured with puretone beeps) returns to normal, that there can be permanent neural damage.

Is there an app that can assess whether I have experienced TTS?

Indeed there is- it is called Temporary Hearing Loss Test app and is available on both the Apple iOS platform and the Android platform. One can use their Smartphone to measure one’s hearing at 6000 Hz (just above the top note on the piano) before a gig or a noisy event, and then after the gig or event. The difference is calculated and expressed as a green coloured screen if the TTS is minimal, an amber coloured screen if there is a greater TTS, and a red coloured screen if the TTS is significant enough to be concerned about.
