[QUOTE="Daniel Postilnik, post: 8114, member: 184"] Hi guys, I know there is a section of this forum for measurement, and this post involves that partially, but it's really a product query. In the fitness industry the fact of the matter is that a certain SPL is necessary to maintain the energy level in a room during certain kinds of classes. However, you can avoid damaging the hearing of customers and instructors. I'm looking for a product that will be able to indicate to someone leading a fitness class if they are operating in a safe range, which could otherwise be difficult to tell if they have been exposed to higher SPL for a while. They It would also be good to be able to collect historical SPL data, such as how loud it gets over the course of a class. I'm not interested in dosimeters because nobody is being exposed to loud music for 8 hours at a time. However, if people are exposed to 105dbA for 45 minutes from speakers that are 6-8 feet away, I still consider that to be dangerous (it certainly hurts my ears and I'm 26). I found one product that could notify fitness instructors if they're over a certain level: SL130G - Sound Level Alert with Alarm However, this can't log data, though there are a number of products that can. Do any of know of a product that has an alarm function and can log SPL data? Thanks! [/QUOTE]
