I've measured sound levels all over the place. But I'm not sure I'd say
there is, for instance, a typical sound level for a beach. Or any other
type of location. Each site is it's own thing on this.
It is rare to find a site that goes below 20 dBA for a average. Though
I've measured a few, and short silent times can be much quieter. Typical
of my nature recording sites where I can get a good recording is 20-40
dBA on slow averaging on the meter. But, I have no average level for
such sites.
After all, frogs have been measured at above 125 dBA for their calls.
And it's frogs I'm recording.
