does anyone know the Decibels or hertz rating

You forgot the question mark showing your sentence is an interrogative. Can you not read the 139db stated right in the description?

The description is a little deceptive. 139db at 6 inches, 115 at 6 feet. Extremely loud either way but not 139db at a useful range.

Loudness mfg rated it at: Low tone harmonized sound. -115 dB/139 dB (at 2 meters/at 4 inches from the source). The tone produced I am guessing is about in the 800-1000 hz range. go to he mfg web site and you can hear the sound that is produced.

Not sure. More than enuff for average listening. If I have to crank it up because it is loud in the shop it drains the battery faster. If you don't care about the battery... It is ridiculous!!!!

I don't know in dbs as I have no way of measuring. I have this on my car and it is loud when car is not running. When tuning I can't hear it. Hope that helps

I don't know decibels but it is very quiet. It's in a room that has no other noise and I can barely hear it on full speed (I put a rheostat on it). Hope this helps. Kind regards.

I'm sorry, I don't have a decibel meter, so I can't give an accurate answer. but it's loud enough to give a good boost to the sound on my Chromebook.

I don't know what the decibel rating is, but it is not excessively loud. Any of the machines you'd be collecting dust off of will be louder (Dewalt 12" bench top planer in my case) so you'd be wearing ear protection anyway. It does draw 15 amps so needs it's own circuit. I couldn't run both the planer and the dust collector off the same circuit without drawing down the voltage. Seems like a solid, well built machine. I've used the older version before with the bag on top which did a satisfactory job. This is definitely an improvement.

This pump is very quiet, one of the reasons I picked it. I don't have any idea of the decibel level.

I believe it is 4.25 tuned to 37hz, with woofer displacement(depending on driver) it moves the tuning up to about 40hz. Some subs might like 40hz, but most 15"s want a bit lower than that for best performance. Also the port area is pretty small, if you front fire it and care about noise, you'll hear port noise from about 40hz through a little over 50hz.

+/-12dB, tunable from 32 to 16K Hz with an advanced equalizer, modifiable surround sound (have to get the software off the web; easier said than done). Hope that answered your question

I can't say what the decibels is but can say that it is loud. I wear ear plugs and it seems to take care of the problem for me. I feel that the suction and cleaning power of this vacuumdefinitely off set the negative sound.

The full range of frequencies, 88.1-107. It's funny that you asked that bc I just read that on the user guide yesterday lol!

Hey, its a good question - from their own package it reads as followed: 101(-+)/-3dB at 1KHz, 1mW. I didn't research any further or look up independent sources to confirm. Hope this helps.

US 60hz... wait maybe not. I will have to go home and check it out. I'll get back to you.

not sure about the hertz. all it says on it is "128 C". i don't recall it coming with instruction. i am not trained, just hit on my palm and it goes.

A 4 cubic foot ported box tuned to 32hz. I have two in my car, for the price they are great.
