I'm not very clued up when it comes to this. Recordings whether music or movies produces dbs at least 15-20 db higher than the desired level, ie. if processor is at 75db the spl during playback is 15-20 dbs higher.
According to THX standards 85db is where you wanna be playing at to hear what the engineers were intending to be heard and you need enough headroom to accomodate 15-20 dbs to accommodate the dynamic range in the recording. So if you set volume at 80db during playback you are at 95-100 db.
Most systems may not be strong enough to still give +-20 db headroom at this level. Is this inconsistency between pink noise and playback unique to my system?
What does this mean in the real world? I'm asking this because most systems listened to at 75-80db as per the volume reading May be playing at a much higher level than the owner think it is. If this is the case this will lead to clipping and damage to the ears and gear during those peak levels during playback as the system is probably pushed to way beyond 100db.
What do you guys think about this?
