Instruments Frequency Ranges and Hearing Test

This is a twofold post,one,what instruments fall into what frequency ranges,and two, testing your hearing!
Instruments frequencies is a good thing to know when recording and mixing.Noise is easily created by adding EQ to an instrument on a track that is not even in that instruments EQ range!Look at the charts to see the frequencies of the instruments,and use it for a guide in EQing your mixes.
And,when was the last time you tested your hearing?I know i have personally damaged my hearing.The test your hearing links here will help you find out the damage you have done to your own personal hearing.And in addition will hopefully raise your awareness on just how important hearing can be for the musician!
The first link/hearing test is,to me,the best one.It covers from 20Hz to 20 Khz,and also allows for volume adjustment.Where as the YouTube link has problems with compression in the higher frequencies.
My test revealed i could not hear beyond 13 Khz.And i was surprised i could hear all the way up to there,from 20 Hz!If you are using speakers and not headphones,your speakers will obviously have to cover all the frequencies played!Headphones of a decent quality usually cover from 20 Hz to 20 Khz.And be very,very careful on the amount of volume!!!Just doing the test can damage your hearing!!!
