    Give some feedback Bud - sounds interesting.

    I have the feeling that levels will be up around 120-130 dB peak - which is well up there for damage to ears. Worst I think is very confined spaces where sound cannot dissipate, plus the peak is effectively a short duration shockwave - about the worst for ear drum.

    I am imagining even my NAA mini with 22 mag's will be well painful in confines of a room. Outdoors certainly not gonna be quite so grim.

    IIRC dB's are not absolute units but, relative to some chosen datum - with sound I seem to recall it is a measure of energy, on a logarithmic scale - each 3 dB step is a doubling or halving.

    Yea, dB is a logarithmic scale, and each 6 decibel increase is equivalent to a doubling of actual sound pressure.
