(Pardon me I am obviously very new to the electric guitar)
Can you do any damage to your hearing if you put your gain/distortion up too high (without putting actual volume that loud)?
For example what if you put your amp's Gain level = 10, Drive volume = 2, then turn your Guitar volume = 7 or something.
The reason I ask is because I saw the following on a website and I guess I had a poor understanding of what it was talking about (wondering if distortion/gain effects on a guitar amp have anything to do with what the website is talking about):

The simple decibel level used does not take into consideration the frequency BANDs in which the sound energy is concentrated (and certain of these, from 1 to 4 kHz, present greater hearing danger), INFRASONIC vibrations, AMPLITUDE MODULATION effects, time variation in sound levels, IMPACT SOUNDs, etc. All of these factors may cause annoyance and create a potential health hazard. See also: EQUIVALENT ENERGY LEVEL.
Recent investigation has shown that average sound levels are not an adequate indicator of hearing risk. Instead, the impulsive character of the sound, in addition to its average intensity level, must be considered. This has been ignored in the past because, first of all, most SOUND LEVEL METERs, even with fast response modes, have an averaging time of about 125 ms, whereas impulse peaks in many sounds occur within 25-50 microseconds. Therefore these meters are unable to measure the true intensity level of such sounds. Moreover, the averaging time of the brain is about 35 ms, and therefore these impulses are actually more intensive than they appear to be based on LOUDNESS. This may be verified by noting that short impulses sound less loud than longer ones of the same intensity. See: CLICK.
Br*el concludes that "we must not only determine the sound level with a normal sound level meter, but must furthermore determine the impulsive content of the noise with a sound level meter that can be charged up very quickly." Such a meter has a 'peak hold' circuit with an averaging time of 30 microseconds. When various sounds are measured with such a meter, it is found that certain ones have very high peak levels compared with fast dBA or dBA impulse hold levels, and therefore these pose a greater hearing risk than those without such impulses.
The worst cases are all impact sounds, metalworking machines (punch presses, nailing machines) and bottling machines. More common domestic sounds that fall into this category are lawnmowers, typewriters, electric shavers, interior car noise and clicks in telephone circuitry. Amplified music, on the other hand, does not contain harmful peaks because of dynamic COMPRESSION. Therefore, hearing loss from exposure to loud music, although significant, is not as extensive as the high levels would normally lead one to predict on the basis of levels alone. The damage-risk criteria that have been suggested to take impulsive content into consideration are shown below.
