Acoustimeter

Post by Lynnie » Sat Jul 06, 2019 11:32 am

I've finally ordered my Acoustimeter. I've read the manual a few times and also EMF Solutions have a sample of sound files so I can start to get used to the different sounds.

https://emfields-solutions.com/rf/

I'm probably going to have a few questions as I start to get used to it so I'm hoping Grahame (as I know you have an Acoustimeter) you'll be willing to help me?

So firstly, on the sound files it has 'background hiss' - would be the sound it makes as a basic noise whether or not it detects any other EMFs?

Also, if there was no EMFs, no wi-fi, no dect etc at all, I've read that it would still make little clicks and beeps as it's detecting its own internal wiring but that's the only sound it would make? Would the light indicators stay at the low end of the meter or not make any sound at all? What I'm trying to find out is if there was no EMFs at all in a house, how would the Acoustimeter show that?

Thirdly, if you walked into a room that had for example wifi and a DECT unit, would the unit make both noises at the same?

Thanks.

It doesn't make much noise at all if there's nothing to detect. The background hiss is 'white noise', which is the sound of the Big Bang! Cosmic Background Radiation, which is everywhere. You used to get it on analogue TVs between channels; I used to turn the volume of it up to full in hotel rooms if I had to get to sleep during the day!

If there are no lights showing on the meter, the levels are well below the Bioinitiave report minimum levels and not worth worrying about. You won't notice the minor clicks The lights are the best guide of the levels.

Yes, usually it's a cacophony of noise. You have to learn to distinguish the sounds. Often moving the meter around a bit will help to separate them a little.

Thanks Grahame, much appreciated.

With the background hiss which is white noise, are their health concerns re white noise (like wifi for example)? I've not heard of EMF sensitivity to white noise - or is there a sound for it because the meter would pick it up and users need to distinguish between harmless background noise and wifi for example? I'm not explaining myself very well but what I would like to know is if my meter picked up nothing but a high background hiss/white noise, would that be something to be concerned about?

No. White noise is the natural state of things, we've evolved with it. It's normal and healthy.

Thanks Grahame, 'white noise' - one less thing to be concerned about. :)

I have a friend who is interested in getting their house tested, when I have accumulated enough knowledge and experience. However, they have an electric substation near their property which they want me to test but I'm not sure the Acoustimeter can read that? I'm assuming that a GSM mobile phone base station (which is does test) would be a different animal from an electric substation?

An entirely different animal - totally different frequency range.
