How about a cheap tape recorder? You could pick up a battery operated
unit very inexpensively secondhand (and for not much more brand new).
It's cheap, simple and a (still) large installed base of tape players
means you can play the recording almost anywhere.
What you really want to do is look at the microphone you are using. I
think you'll want a microphone with an omnidirectional pickup pattern
and the ability to pick up sounds from afar.
Unidirectional and "noise canceling" microphones are probably not
going to work well for this application.

As mentioned above, a tape deck is cheap and effective. A second hand
stereo one (be sure to get one with mic inputs) and a couple of good
mikes will knock the socks off any mp3 type device, for the same or
less money.

It's going to be a good starting point. But almost any portable cassetteThank you for your reply. I fear you are correct that the front end
is most important - the mike and preamp.
A tape won't match that, but my thought is to wait until the noise occursIn defense of digital vs mechanical, the Sony has 1 1/2 hr of
'perfect' MP3 and more than 340 hours of plain recording
Consider going further than that -- play the unit into your stereo receiver.I just realized I was playing the sound back using the built in 1 inch
diameter speaker. Duh! Will try using earphones with better fidelity
to see if the lower spectrum exists.
While that sounds very interesting, why do you want to do that? It soundsso I can do some very esoteric manipulations using a Matlab clone, octave.

You don't need ultra-high-fidelity to capture a record of someone's making a
disturbingly loud amount of sound. The cheap point is rendered moot by the
presence of the more expensive recorder, yet the simplicity and still
massive installed base of playback equipment can't be argued. Plus, the tape
recorder has the advantage in cost--if something happens to it, you aren't
out a fortune!

The recorder isn't as important as the microphone and the playback
loudspeaker.
Is the noise coming through in one place (e.g. hammer drilling or tap
dancing) or is it diffuse? If it is diffuse, an omnidirectional mic
might work best.
If the noise is predominantly low frequency (e.g. boom box) a cheap
omnidirectional mic will generally have a better low frequency response
than a cheap cardioid. The big problem you will have with L.F. noise is
demonstrating it realistically to someone, because loudspeakers are
rarely flat at such frequencies and the bass from headphones will depend
on their positioning on the listener's ears.
Investment in a cheap analogue sound level meter will help; then you can
calibrate the recording level and match the playback level to it when
you come to demonstrate the problem. Use the dBC scale if the noise is
predominantly L.F.

Rubbish. Once his CD quality recording is made, with what he has at the
moment, it can then easily be transferred to a PC via USB into free editing
software like Audacity, where you can do all the equalising, level shifting,
noise reduction and analysis you like. You can't do much of that with a
Cassette Player.

Why? A recording would prove nothing. You need to measure sound
levels, not record the sounds. A sensitive microphone would pick up
the smallest of sounds so there would be no way to determine that the
neighbor's noise/sounds were a problem or not. As well, what does your
lease say on noise, and his? If it is not covered, prepair for a long
hard time.

then through our ceiling. It is possible to tell origin, but it's
like a spotlight diffused onto a sheet of paper - you can tell where

a large courtroom...
There used to be a simple SPL meter, with analogue readout, availableAny recommendations for readily available sound level meters? the
Sony has vu meters on it, but I think they're relative and not
absolute.
Well Put!!!This yet another example of a question that should have had a single
response, with the thread ending at that point.
You do not need a recorder, except perhaps to make a record of what is
disturbing you. You need to borrow a sound-level meter to measure how loud
the disturbance is. Otherwise, there is no good reason for the management to
believe you.
----- The Lady from Philadelphia
Excellent advice. Listen to the man...You can demonstrate the exact effect you have been suffering to any
official who comes to visit you, but a meter reading in dBC, coupled
with a log of the times it occurs, is often sufficient to convince them.
You wouldn't normally be expected to demonstrate it in a court.
Unless the noise is of some particularly irritating character or
requires specialist identification, you may not need to record it at
all. The action you take will depend on three properties of the noise:
1) Its loudness
2) What time of day or night it occurs - and for how long
3) Its annoyance factor (is it a hum, intermittent banging noises,
thudding bass, sounds of a murder, bagpipe practice?)
...only the third property might need a recording to demonstrate the
point you want to make.
