Where is ear level measured? Just with a mic in free space? What's the difference in dB between ear level and in ear measurements, aside from gain above 1 kHz and so on due to the pinna and so on? What's the difference in levels?
My guess would be that something narrowband with X dB SPL total could be more damaging than something broadband with X dB SPL total, and so on. Is that right?
All I know is that A weighting is kind of abused in a lot of contexts. It probably doesn't mean too much useful at higher levels, for music-like sounds.
The SPL values that are said to cause hearing damage at such a level and comfortable listening levels and such are A-weighted, full-spectrum SPL ("slow"), and at ear level (not in-ear). This is not directly comparable to the SPL in the sensitivity measurement.
