Thatis quite a high figure ,John. Similar to a small tranny radio in metre box which would be bad to live with at higher frequencies. The human ear is not very efficient around 40Hz so this must be what makes it more bearable to many of us [not all]. It does give hope that, whatever the obsfucation of the authorities, here and there, it is something seriously capable of measurement in ordinary daily life. Keep up the good work. Can one assume that the level quoted reflects the average level of your plot output?
