You are right and I also know about this bias. Emotionally I'm more comfortable with my own lies. I think I'm a typical man, I like to feel that "I did it my way".
You have answered the question yourself.
I don't have the talent to tell between good scientist to a bad one. Most times I look at their photo and if they look honest I believe them. If she is good looking scientist I believe every word she say. I also know that the honest man in the photo isn't the scientist, he is a manager paid to quote the modified report. I fall for it anyway.
I worked for several firms, whenever we had an unhappy customer I lied to him without feeling guilty because I was loyal to the firm.
I think people on this forum are telling the truth all the time because nobody pays them.
It's a catch 22.

If you hear more noise when one ear is blocked then that is normal. I think we have two ears and hear in stereo not as a backup in case one ear is chopped off, but stereo allows your brain to cancel noises that are usually in mono (the same sound or noise in both ears). Echoes are horrible in mono but are easily cancelled in stereo, try it.
If you add what you say to what audioguru said about stereo and noise it will be easy for you to understand why some people are very disturbed by low frequencies sound.Our dogs used to get fed at exactly 6pm. At that time, the local news show starts on TV and they got used to the opening theme song just before getting fed. Now when they hear that song they get excited. Funny how they are able to distinguish different kinds of music.
I play music too, but always seemed to have a difficult time identifying the bass notes. One day at the lab I was listening to an audio circuit with a low frequency signal to listen for distortion artifacts. I removed the headphones when interrupted and when I put them on again the sound was in the wrong ear. I swapped the sides and noticed that the pitch seemed to be exactly one semitone higher. Huh????
Over the next hour or so, I tried a lot of different frequencies in either ear and discovered that ONLY in the range of maybe 150 to 250 Hz, a pitch in the right ear and my left ear seems to be about one semitone apart. All other frequency ranges seem consistent from ear to ear. I mean I literally hear a note in my left ear, then move the speaker over to my right ear, and it really sounds like a different note is being played!
I think I discovered something really unusual here. I think that may account for my difficulty in determining pitch of bass notes. Never heard or read of such an effect before or since.
Your story supports my theory that people with good hearing are more likely to get tinnitus.Today I am 69 years old, still love music and can still hear frequencies pretty high but not ultrasonic frequencies anymore. I think I have tinnitus because I hear very high pitched background noise all the time. But I take a small Asprin every day to keep my arteries working and high doses are said to cause tinnitus. I think tinnitus is caused by the high frequency nerves are not damped by damaged high frequency transducers (hairs inside the cochlea?) anymore. I read today that when your doctor can also hear your tinnitus then you have a serious medical problem with blood flow (like a faucet that squeals).
Could it be because you are listening to MP3?When music went digital, I seemed to have lost interest in music and even the ATSC DTV. My nice 1970's stereo has been in disrepair for a while.
By nice, I mean a 0-100 kHz in the pre-amp stages and 0.5 Khz - 40 Hz for the output with both multipath processors (Carver) and a dynamic range processor with derivative processing (speeds up rise time) by a dbx 4bx. A 12 band EQ also with a response out to 100 Khz.
The amp has been compared with a Mcintosh tube amp running to Voice of the theater speakers with horns. The low wattage tube amp could really drive the horns louder than my 100 W amp could. Bass was much better with the solid state amp. The sound was comparable except for those differences. My friend likes classical music and I like high rise time stuff (Dome tweeter material) e.g. Hammer dulcimer or Folk music.
I've tried your meter but the readings don't look right.You need to develope your inner
If you have music that you know well on a CD compress it to MP4 and try the difference. Some say that compression kill the music.Yep, I suppose so. ATSC is MP4 sound. So, even the FM stations are probably playing MP3's.
Thank you for the reply.I played fairly loud music all my life that might have damaged my hearing and produced tinnitus. But my age also might have produced the tinnitus even if I did not damage my hearing.
I do not "hear" my pc or CRT TV.
I worked with Altec sound equipment. Their huge Voice Of The Theater speakers were designed to be as loud as possible to fill a theater with plenty of sound from a low power tube amplifier. They were ported "boom boxes" that resonated one-note-bass and the high output impedance of tube amplifiers did not damp the resonance. The horn mid-tweeters shrieked awful peaky and distorted sounds.
I like modern smaller speakers designed for good wideband sound not high volume from low power amps. I also like the very flat frequency response and low distortion from dome tweeters.
