Thread: How loud is your Isuzu?

What's the name of the app you used? If its a freebie (or close) I'll give a try and let you know.

Think the app was called "TOO LOUD" (it's on the other halfs phone). It is free. The way you calibrate it seems a bit dodgy, but I don't know a better way of doing it.

I think the accuracy of your measurement would be VERY dodgy.

Offender90 is an acoustics engineer, and has done measurements of his (very noisy at the time) isuzu 120 ute, and posted the measurements up here (search under his username).

Edit - here we go:
Isuzu 4BD1 Vs. 300tdi sound check

As for "Too Loud" - 85 dBA is the current legislated limit for an 8 hr occupational exposure AFAIK.

At highway speeds, mine is less noisy than a 300tdi Defender, and not too different to a Puma 110, according to a Puma owner who has come for a ride once or twice.
Around town is very different...

Lro mag did an article on sound proofing a td5 in the uk this what they came up with
30mph before 76db after 64db
50 72 69
60 78 71
75 83 78

Ummm .... I might have missed something here, but I would have thought that an app called 'Too Loud' would only be used by males??

Sorry .... prone to brain snaps today.

Looks like I'll need to go for a run in a Defender and have a listen for myself. Haven't been in one for ages, but dont remember them being too bad. I dont think the County is that bad either, just end up with a ringing head after a long trip - but who cares.
As for your comment circlework, I am the one that uses the app, its just that its on her phone!

I have a proper DB Meter & after spending countless hours & $500 on sound deadening mine was 82 db @ 100kph.
