Title: BOW NOISE
Post by: kennym on April 15, 2017, 03:29:00 PM
Anybody ever check it? I bought a cheap db meter, and the findings are following:

Right at 500 grn arrow-
64" original D/R ------------ 70 db
64" mod D/r ------------------72 db
58" forward handle D/R -------71 db
snapping a loose nock on------56 db
snapping a bit tighter nock---61 db
table saw freewheeling -------91 db
band saw freewheeling --------66 db
AC/DC Dirty Deeds-------------300 db (just kiddin)

So I guess the added oomph of the mod d/r are worth it maybe.

Those readings are higher than I would have expected.  I think OSHA requires hearing protection at 85 db, of course I think eack db doubles the volume or something like that.  Thankfully I have been retired long enough I don't recall LOL.

Interesting, what type of sting silencers?

Rubber cat whiskers , short ones . It reads 32 or so with just the wind outside the building.

From OSHA

Employers are required to measure noise levels; provide free annual hearing exams, hearing protection, and training; and conduct evaluations of the adequacy of the hearing protectors in use (unless changes made to tools, equipment, and schedules result in worker noise exposure levels that are less than the 85 dBA).

And if you wanna really get into it, read this...

That's really interesting! It would be a lot of fun to play around with on if those.

It was pretty cheap, think about $16.00, figured it would give a baseline even if it wasn't super accurate.

I have one on my phone but it's hard to say about accuracy.

LOL Randy!

Roy, it probably maxed out around 614 db, I suspect it sounded like a squatch with his privates caught in a fence.  :laughing:

Kenny when I was working at the pro shop we had the time and equipment to tune the string of a trad bow using the placement of the silencers. Our best understanding was it smoothed out the harmonic wave kinda like tuning harmonic nodes on a precision rifle.  The closer to the tips the silencers are the less effect they have on the string but if you have the time use the db meter and chrono to tune them and see what happens. Also try the same arrows with a parabolic cut feather vs a shield just for funzys

You guys drive me up a wall. I thought stick bows was a keep it simple thing. Now they are turning into a computer generated print out, just like compounds? LOL...

The trad bow is only simple for simple minded  ;)

Curiosity Roy Boy.   :D   Just wanted to see if improved performance meant more noise too. Didn't seem to in this case.

I have discovered that all my bows are much quieter when I take my hearing aids out  :knothead:

I agree.......and disagree. Lol
I wanna keep things simple, but might as well be as effecient  as possible while being simple.

You glass bow making girls crack me up.I will put my wooden bows up against any of your glass bows in a db test. And win.

db= decibel or durability?  :laughing:

Yeeee Haaaa!   :laughing:

C'mon out, Roy, we'll fire up the DB meter.

I'm betting that they get quieter in direct relationship to the accumulation of emptys.   :)

The bow I was going to hunt turkeys with next week was damn near silent, until it made a loud POP!    :(  
I would love to see just how my bows compare to similar glass bows for noise.
Dave.

It would be neat to also see how many decibels glass ASL bows are. Most people say that style of bow (Hill-style bows in particular) are extremely quiet.

I also wonder how a dedicated decibel meter compares to a smartphone decibel meter app.  Interesting stuff!
