Is it worth considering the different experiences of ‘listening to music at home’ and ‘going to a concert’. In my experience concert going is considerably more sonically rewarding. I would also say that this was not genre specific. I work a lot in rock, pop and dance music but I have recently be

The question isn't whether 'music' has frequencies below 1/zillion Hz. It's whether such content adds to the MUSIC. This is the case ONLY with organs reproduced properly. You can check this with DBLTs. The speaker that has come out top in every single DBLT it has been in nearly 2 decades (som

Considering most popular music these days is of the electronic variety or contains electronic processing. It all contains sub below 30, albeit rolled off down to 20. I don't know of a mix or record I have done that doesn't contain sub below 30. I manage it though to keep some headroom. Sympathetic

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

Legislative bodies almost all use the A weighted scale. This is usually because they are usually environmental health departments. The A weighted scale is useful as it is a good indication if a noise is annoying (usually at night time) which is their prime consideration. It is also available on

I too doubt that most music has sub 20hz material except for some organ and percussion, electronic music and other recordings utilizing sub-harmonic synthesizers. Another obvious source of sub 20hz sound is unwanted environmental noise such as HVAC, traffic etc. Bill Houston Sent from my iPho

I think what people mean when legislation measuring at 100 dB-A is an oxymoron. dBA was meant to mimic the equal-loudness curve at low level of listening (around 40 dB spl @ 1k) and is absolutely not representative of the relatively linear curve around 100 dB SPL @1k. The wikipedia articles on
