    Well there is a relationship between accuracy and cost. A quick google shows devices for a little as €20 but I didn't check any specs.

    I've used Brüel & Kjær stuff in the past and found them good. You could ask your local college if you can rent one.

    If you knew the frequencies of noise and the performance of materials you could use soundproofing to reduce the noise to a measureable amount. Not all materials reduce sound evenly at all frequencies so you might not get away with it for white noise.

    or you could simply measure the sound from further away if you are mixing up dB and dBm ,




    160 dB is kinda loud, close up and prolonged it's somewhere between
    "wow his ears are bleeding" and "we're going to need a mop"

    its for doing some tests with rifles to see how loud they are with and with out sound moderators on them, a few of us in the shooting forum want to see what is the most effective sound moderator (or silencer as they're called in hollywood) and some of the firearms that will be used can be as loud as 160db
    buying a cheap 130db soundmeter and placing it a few metres away might be a good option, thanks for that
