I cant even stress enough the importance of ear protection these days . It is really important if you are a musician that spends allot of time in the studio and live to take good care of your ears because they are after all tools of the trade for you ! Same goes for audio engineers , producers and anybody that spends allot of time with audio !!!
So, remember to use earplugs and earmuffs and keep a low and safe level when mixing , composing , watching a show or playing live !!
80 to 90 db is a good level to keep when mixing for me , i also try not to expose myself to more than 5 minutes at anything louder than 110 db .
Take note as well that you can judge a mix better at lower volumes than at louder ones !!!
Stay safe guys and girls !!
