40 db is too much, in my opinion.Pethical said:im a guitarist. its the most you can get for the price. they are worth every penny, 80$ is not a lot to save your hearing.
110dB - 40dB = 70dB
According to this chart (http://www.gcaudio.com/resources/howtos/loudness.html) 70dB is the volume of normal conversation.
