Doug,
That's not good at all. Is it worth deleting it and downloading another? My app was created by Smart Tools Co. and seems to work very well.
If I shut myself into a quiet room late at night it reads just below zero ... as it should. The highest reading I got was 97. Difficult to believe it is your microphone ... got to be the software.

You have me worried now John. NCArcher contacted me and detailed the connections for me and after checking last night I am almost 100% sure the sparky has them right.
The input to VFD is red RL1, black is SL2. According to Chris and NCArcher it doesn't really matter wether black is to TL3 or SL2.
The output from VSD is red to UT1, Blue is VT2 and white is WT3.
The input to motor is blue to W1, White to V1 and red to U1.
Metal connections run across to V2 U2 and W2 and the green earth at both ends(not a shielded cable)
Does this differ from yours?
It might help if we can sought this because apparently there have been a few faults caused by sparkies who have had little experience on the electronic side and it might help others setting their cyclone up.

Doug,
Does not compute ...
I was taking readings with mine yesterday, 16 M from the cyclone (outside). When the birds chirped the meter jumped around. If a car drove by (100 M away), you could watch the reading climb and fall with the passing of the car. Had to lock my dog inside because he wanted to growl at the birds, and even a soft, low growl was resulting in a jump in the readings. A bark jumped to about 90 dB.
If the microphone in your phone works OK for conversation, it should do better than you indicate.
That's weird Something is not right.

Sounds like you are hooked up for star (415V) and not delta (240V). Mine was like that, but my motor still ran ... and buggered up the VFD.
Look at your compliance plate on the motor and at the diagram on the inside of the wiring cover for the motor. Star looks like a three pointed asterisk ... that's the arrangement for 415 V. Delta is shown as a triangle ... that's the hook-up for 240 V, and is what you should have, assuming you do not have 3 phase power and are hooked up to 240 V.
For delta (assuming we have the same motor) U1 should be connected to W2 ... V1 should be connected to U2 ... W1 should be connected to V2. (Your compliance plate and the diagram on the inside of the wiring cover on the motor illustrate correct connections for star and delta)
Another way to put it is this. Look at the metal connectors. Assuming your motor is like mine, if they are vertical, you are wired for star. They should be horizontal.
Sounds like we both got sparkies who know zip about wiring motors. I hired a sparky to be sure I got it right ... but he made a dumb mistake I would not have made. I would have followed the wiring diagram faithfully because as a sparky I would make a great cricketer. Knowing nothing, one follows the diagram ... exactly.
Finally, once you get the motor spinning, make sure it spins the right way. If it does not, switch any two of the three wires (excluding the earth) on the VFD, and it will spin the right way (this instruction is in your manual).
Good luck!

That really depends where your live. To get a zero reading there has to be no traffic within a couple of km, zero wind outside and the temperature has to be relatively constant as warming and cooling houses make noises across the frequency range. If this is not your situation then the meter is not reading correctly. The lowest I saw my iPhone app reading go inside the house during yesterday was 30 dB - this is also the lowest reading I get in my shed. We are 5 km from a major freeway and ringed by a major highways and major roads. When the wind is blowing in the right directions we can hear some animals at the zoo about 4 km away

Bob,
I'm sure you are right, but at night the back of the house is very quiet. My tests yesterday show the microphone following the inverse proportional law as theory predicts. It is likely my instrument is not perfectly calibrated (if it is out, I reckon it might read a little low), but its response looks pretty good. As I type there is a bird several metres away from my window. Every time it chirps the meter jumps about 10-20 dB, and I can watch the plot of values rise and fall as a car drives past 100 M away. When taking readings yesterday, I needed to wait for the wind to drop, because the rustling of the leaves lifted the readings. I cannot move when taking readings below about 30 dB, because even a soft foot fall registers on the instrument.
Of course, zero decibels is not zero sound. It is the reference level, so when things get very, very quiet, the readings should fall below zero. Nevertheless, because I don't know how good my calibration is, I cannot trust the absolute readings. As you indicated earlier, that does not really matter if all I want is to know whether or not things are getting quieter. I am confident the instrument does that reasonably well.

He could not get it any closer to the roof than my original installation.

I have never seen any factory noise figures for a cyclone with or without an open exhaust. I have always used mine as the yard stick when making people aware that they are damned noisy. I have heard others say they are around mine so have no reason to question my readings.

John, I am away for easter so can't absolutely confirm but when I looked on Friday I am sure the metal connectors are horizontal. On the motor cover the diagram for star shows that the left hand terminal should be connected vertically not horizontal as for Delta.
