I think my use of the word significant was unwise but I would be interested to hear from anyone else who has looked in the lower spectrum below 30 Hz and found content. In measurements I made, just looking at a local orchestra, there was energy going down below 20hz The heating system was clearly registered at a steady 16hz but this noise was dynamic and matching that of the instruments. This was popular symphonic music, modern dance music as you surmised features much higher levels. Regards Jon
