    worked in hearing conservation for a few years. Not sure what you're asking but 80 dBA for 8 hours gives some people a hearing loss. That's the same as 85 dBA for 4 hours or 90 dBA (A-weighted) for 2 hours.

    THe fact as an instructor you'll also be yelling OVER the music won't help either. So put the speakers AWAY from you and don't turn them up too loud.
    Some of your students don't like the music that loud anyway.

    It seems like I remember the trainer that taught the instructor's class (she was outta town, not from our gym) had a rating of what was deemed as acceptable decible level in class. Might have her email somewhere, or sending one to the spin program directly.

    Realize other factors contribute the overal accumulative effect of hearing loss... like what you do at work, etc.

    I almost feel like it's a bit worse in my left ear. As an outdoor road cyclists as well, I plan to ask the ENT doc if the noise exposure of vehicels passing you on the left side next to that ear (for those of you in the US, right side of road driving, cars/loud trucks/motorcycles etc. going around you on the left) could attribute to the overall effect.

    When I teach, my classes will be within whatever the said acceptable level is. Frankly, I plan to bring the issue up to the management thinking about it more. Thx for the thoughts.

    How are you measuring the noise level?

    If you ride where there are lots of cars passing you, you bet it is going to affect you.
    Hearing loss can be proven from just attending 1 rock concert!

    wear earplugs (or AN earplug) in that spin class

    The above link goes to a device that someone in the music biz told me about. The product description discusses using it for measuring music mixes etc., BUT it measure overall sound decible levels. Obviously on the gym stero, you'd just set it next to the speaker and get the read. On the bike, gosh... if you really wanted to measure it, suppose it could be affixed somewhere for a test and trial. But, I would think the ENT specialist would be able to quote off the top on what levels a car produces, large truck, motor cycle accelerating etc. Just take that, and think about the multiplication of times being passed on a various length rides! Obviously we need to hear the traffic coming up behind us for safety. But if the one ear is prone to exposure, then one plug mght be a saver. Adding that on the list to discuss with the doc.

    Test sound levels at each bike (including the instructor's), not at the speakers. Do your normal cueing while you're testing it, so you get your voice level in there, too.

    This is tough because a lot of instructors and students like their music VERY loud. I actually complained about it at a fitness convention I went to this fall, and there's one aerobics instructor at our gym that if I'm going to take her class, I wear earplugs (bright orange ones so everyone knows). But when I measured the levels in her class, it was "only" 86-87 dB - truly painful for me, but well below OSHA regulation for a one-hour class.

    ONLY???
    ow, i agree!

    and perhaps an authority figure (like the spin instructor) needs to tell these people what for?

    I thought so too. The older gent is a "fuddy duddy" the sensible instructor is a "stick in the mud" .... this would make me want to skip the gym and all classes and go outside and ride.

    Just give me good music, acceptable but safe volume, some actual training - teach me something, supportive enviornment, that's a class.
