Need a sound recorder for recording noise intrusion from an adjacent

Using Sony ICD-SX700 did not achieve very good results.

What should I use?

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.

Why on earth would anyone recommend buying a last century Cassette Deck, the
OP already has a digital recorder capable of 16 bit 44.1k recordings, the
same quality of CD.

You might be able to improve the recordings by using a better quality
external mic plugged into the mic input jack and placed accordingly.

I suspect though that the problem is not the equipment, but rather the
unrealistic expectations of the OP.
