That's interesting .I remember the Ohm speakers of the 80's. In fact, I was talking to a co worker last summer. He's a music freak like us. He mentioned his favorite speaker of all time was those Walsh OHm's ..

A few years ago one of our members who performs professionally in a classical symphony orchestra posted the following, in this thread. I would emphasize the words "continuous time weighted average" in his post. Recently, there was a post on the ICSOM board that I thought I would share the info from. ICSOM is the International Congress of Symphony and Opera Musicians, which consists of the musicians of the major US and some international orchestras.Regards, -- Al |
Almarg: Not sure about the word "noise" in your post. Music at 95db from acoustical instruments is not dangerous at all. Noise, however, can be troublesome as loud as 90 db. Am considering "noise" to be random in nature and not periodic as is music. Regularly play on a piano at 95 db and it is not at all stressful. When I listen to a sound system at the same level, however, it sounds loud -- and can be stressful if there is any noise (=hiss) or distortion. Know a number of symphonic musicians who are 65+ years old and they hear fine after playing loud symphonies all their life. They do, of course, worry about their sound exposure and take certain precautions. I share a number of the views above about the dangers of listening to recorded music at the 105-110db level. Have done DB tests with my audio systems and find this dangerously loud. The more you listen to very loud audio, the more deadened your hearing becomes and you tend to up the volume to recapture the pleasurable sense of "loud." Take an hour off, instead, and return to the level you were listening at -- you will notice how much louder this is than you earlier had thought. |
Al Everybody that has ever been to a 3 hour rock concert, or a drag, circle, or road course race ( Like Nascar) ...just flunked. I'm assuming you do none of these . We are not all built alike.. Cigarettes,lack of seat belts and helmets, obesity . There are a lot of things that are a no no . Do you wanna die from it, or go to your grave craving it ... |
I dont think audiologists have a clue. All we know is for sure that super loud prolonged exposure is bad - gunshots, cannon etc can cause instant damage. Rock concerts are damaging. Another big factor is aging - hearing (like eye sight) deteriorates with age - some much faster than others. I agree that giving ears a break is crucial. Avoiding loud rock concerts. Also avoiding instantaneous damage from loud explosions is key. It appears that continuous background noise is also bad (engine noise in a mechanical room or factory). I suspect ear buds are very bad as low frequencies are trapped in the ear between the bud and ear. Natural variability in the individual makes it so hard to generalize. |
