Another thing not mentioned in several of these sites is distance to sound producer. Distance affects the intensity of an isotropic radiator by the inverse square. So either these measurements are made up close to the instruments (literally inches away), or there are serious calibration errors with the instrument doing the measurement.
Weighting makes a 9dB difference with orchestral music, so the maximum unweighted sound pressure that I've seen with an orchestra is still under 110dB in the front row. The high 90s is more like it for A-weighted measurements. A hotel orchestra would come in even lower than this.
Club bands (amplified ballad rock) seem to peak at around 114dB (flat).
I frequently get a kick out of all the absurd SPL readings that competition car audio systems supposedly generate.

Regarding hearing, back when I was in my early twenties, I could hear bats' sonar shrieks at night in the park, where one could see the bats flying around and roosting in the willow trees. Those were the days.. When the first FM stereophonic multiplex broadcasts started happening, I remember being able to tell a station broadcasting stereo by the audible (to my ears) 19Kc pilot tone. In 1962, Lester Karg gave me one of his laboratory FM tuners, which I have had for over 35 years, and I could hear pilot tones on this tuner as well, because the low pass filter was only 6dB.oct slope. I never bought the Knight Kit stereo adapter for it, as my system back then was mono, with a single Aristocrat KD6 speaker enclosure. I had Bozak tweeters that Rudy Bozak gave me when he had his plant near where I lived at the time in Stamford, and they were about the best there was at that time, extending all the way to 20Kc. As such, I had no difficulty hearing the FM stereo pilot tones.

But now today I can't even hear the UPS truck pull up my driveway for a delivery.

Anyone want to loan me their headphones? Mine broke around the time I took my test last year but I promise to use them just for a new test. :flex:

I checked my heading using the online programs. My hearing is ok, as I'm middle aged now, I lost sensitivity above 15Khz, and a tad bit in the lowest bass. I'm not sure how accurate the test was because I used some in-ear monitors which roll off above 16Khz but overall my ears seem on course for my age group.

Well I have decided to go to the doctor and get my ear checked out. For the past month my right has sounded a little bit boomy. Sometimes it would begin to feel funny while in the HT and when that would happen I would stop watching movies a couple days for it to feel normal again for many months. I releave the pressure druing movies and it seems to at least feel better. Then this past month the right side of my head has felt sore and my ear would keep poping. Now the soreness is gone on the right side of my head but the ear keeps opening and closing. There has been an unsual amount of build up of ear wax in it. I cannot hear the high pitch noises out of the right side (above 10K) very well today and it occassionaly becomes closed. I am having a difficult time with this. I hope that the doctor can help me, because I have not been able to enjoy the HT.

I do not know if it is directly related to how I have setup my speakers, but the right speaker in my setup has a dip at the same frequency and a peak at the same frequencies I am having problems with as I have setup them by ear. I hope that it is tremporary, and not related to hearing loss caused by my room, and that I will be able to go to the doctor today.

I was advised not to go to the doctor quite yet. I have been using ear wax removal system a couple days and my hearing has returned and it sounds normal. Still has some mild pressure in it so I will have another treatment if it persist, and then see the doc or have a family member borrow a device from the hospital to check in there.
