Low frequency noise analysis

For everything after the recording stage: hardware/software and how you use it.

Ah! Just last week I acquired and used a Garrard turntable for next to nothing, to use as a prop for the lyrics video of my band's next song, due next Friday.

I saw a programme about Star wars last night, the props guy bought some old flash bulb holders from a photographic shop and with a few add ons made them into the light sabres.
Regarding the OP I too had well over a week of intermittent low frequency noise where I live. I posted it on our village’s Facebook page but no one else got back to me. I don’t think I was imagining it though.

Most recent occasion was a mobile blast furnace at 1am while they renewed all the double yellow lines around the entrances/exits of the nearby roundabout.

You would think you would not need double yellows around a roundabout! Who would be daft enough to park there?

Mind you, they ignore the DYs on the junctions at the primary school bottom of my street and all that yellow paint on box junctions is wasted a lot of the time, especially at this time of year.

We've just had the DYs re-painted where I work today. They said it would be loud but, Gordon Bennett, it was deafening. I was awaiting a barrage of complaints from our neighbours which fortunately never happened; but the thought of that work being done at night just doesn't bear thinking about...

Apparently there is the "world wide hum" which not every one can hear.
(not every one is a musician !)

I suffer an LF hum every summer, most noticeably at night.
... It's the next door neighbours ceiling fan :(

Aaargh! :crazy:

They may find it cool (see what I did there?), but it would be most annoying to anyone within earshot who doesn't benefit from the soothing airflow :headbang:
