Need a favor from a GG6 owner that has a decibel meter app

[Coach Steve]

Hey everybody,

My GG6 latest version, is ridiculously loud and most of the noise is being produced by the gears and not as m,uch the motor - if that makes sense. I've read the posts of others who had concerns about the increased noise level vs their previous machines and I get it... they're louder. I get it. However, since the only real way to confirm whether or not mine is louder than I feel it should be is to use a controlled comparison i.e., a decibel meter app.
I just am not comfortable accepting that the noise level mine is emitting is "normal" and end up burning it out. I understand it's covered under warranty but I can't send it in if there isn't some kind of proof that something isn't right.

I chose Sound Meter & Noise Detector 2017 Ver. 1.2 for Android. It's free.

We can figure out the control steps once I get somebody to volunteer to help me out. I would really appreciate any help you are willing to offer with this.

Thanks,
Coach

I don't have a GG6... But I did confirm the noise between the HF DA and the G21.

I'd be willing to bet good money that the HF DA works better than the PC.

And as far as the noise factor... I just did an equal test between the HF DA and the Griots Boss 21. Both had a 5" backing plate on without a pad. Both on speed 5 the same exact distance from my phone.

Both clocked in @87 decibels.

My HF DA is just about as smooth as my Boss during the free spin.

How does your GG6 compare?

I'm in PA, so can't help tonight but I'll give you a reading from a real sound meter in the morning. At what distance did you take your reading?

If the HF is like a Prius, my GG6 sounds like a Chevy 427 with no exhaust system. seriously, it's loud enouggh that I wear ear plugs when I'm using it. The thing is, it wasn't this loud when I first started using it about 6 mos. ago. There wasn't a gradual increase in sound. It was like one day it was what I considered to be appropriate for the power it has and the next time I used it it was noticeably louder. Nothing has changed performance-wise. The thing that concerns me is most of the noise is coming from the gears rather than the electric motor.
I'll shoot a quick video and upload it so others can understand what I mean by the gears making most of the noise.

Let's call it 6" and thanks!

O.K. In fact I'll give you two readings, one from my sound meter, and another from an iPhone app. I'll have to download one because I've never had a need, but now I'm curious to see how close the readings wifi be.

Another control question. What speed setting on the GG6?

[Firehouse Mike]

A sudden increase in noise may be an indication of a bearing going out. I would give Griots a call and talk to their tech support guys. I'm sure you can get a new one from them. My GG6 is actually quieter than my G21.

O.K. Coach, here's some data for you. I'm not going to bother providing the iphone reading because the app suggests trimming the settings using a real sound meter for calibration. Without the calibration the app numbers were running about 4db higher. And of course, after the trimming was added they were the same. So, here is the data from the sound meter using the "A" scale, "slow response", and average reading.

Speed Setting 3: From 6" 86db; From 3' 82db
Speed Setting 6: From 6" 87db; From 3' 84db

A little info about my GG6. It is about 6 months old, and has been used to polish and wax two full size SUV's. I have not noticed any change in noise level since new. I have always had to wear hearing protection when using it in a closed environment such as my garage.

Hope you find this info helpful. What kind of readings have you been getting?

My GG6 is a yr old. Sound the same and it's loud. Always have my ear plugs or iPod on me..
