Uses for a 5 Hz frequency?

In analogue electronics, yes. In digital electronics, no.

Well yes you still can. Whether it's a signal, say between 0.4 and 5v, being read where anything over a certain point is on and anything under a certain point is off irregardless of the wave form. It's also quite easy to digitise any analogue signal using a digital to analogue converter and also create an analogue waveform using an analogue to digital converter though the later can look rough depending on the quantisation level and the former can suffer from aliasing if the sample rate isn't right, normally recommended to be 2 times the sampled signal frequency.
 
Don't a lot of ups receivers need to be set to 5Hz?

Also on the brown noise subject, although it is a myth as far as sound via air, it is different if your body is in contact with something at 5Hz

Air is a very inefficient medium for transferring low frequency vibration from a transducer to the human body. Mechanical connection of the vibration source to the human body, however, provides a potentially dangerous combination. The U.S. space program, worried about the harmful effects of rocket flight on astronauts, ordered vibration tests that used cockpit seats mounted on vibration tables to transfer 'brown note' and other frequencies directly to the human subjects. Very high power levels of 160 dB were achieved at frequencies of 2–3 Hz. Test frequencies ranged from 0.5 Hz to 40 Hz. Test subjects suffered motor ataxia, nausea, visual disturbance, degraded task performance and difficulties in communication. These tests are assumed by researchers to be the nucleus of the current urban myth

Subsonic note?

Does it say if it is sinusoidal or square or whaterver?



Screwed up youth fact correction sheet:
- Brown noise does exist.
- Brown noise does not make you poo.
- 5Hz is not brown noise.
- 5Hz is a subsonic tone.
- Brown noise is not a single tone.
- 5Hz is not the same as 5Ghz.
 
If you're talking about Brownian noise then I agree, but that's the correct name, not brown noise. I've never heard Brownian noise called brown noise :confused:

Oh, and I'm not a youth ;)
 
You should be able to make someone sick between 5hz and 20hz. I ran some through a 1kW amp into an 18" bass driver and made a mate throw up. He had just eaten though, may skew the results.

5hz at high enough volume will seriously disorientate you.
 
thanks guys, way more response than expected, must be a boring day in the office :p

its a digital circuit so square waves, probably go for the "vibrator" and strobe light (i wont actually say a vibrator ill say vibrating device)

i seem to remember seeing brown noise on braniac but cant remember what they concluded......

thanks again

That sounds fun! :D

1kw a fair amount in 18"!

Yeah, that's what I was getting at. Don't they use a similar thing on 'Haunted House' tours and ghost hunts?

at 5hz it would be more of a wiggle than a vibration:D
