If you have an iPhone, you can download the Amplitude Pro app and hold the iPhone to the glass against the wall. This app allows you to hear distant sounds much more clearly, but it also records and saves the amplified noise.
How can I hear my Neighbours through walls?
One method is a simple glass held against the wall. The reason this works is that you create an “acoustic coupling” between the wall and the glass, allowing sound waves to travel from one side to the other. A soda or beer glass works best.

How can I clearly listen through walls?
It's a cliche, but it works. Take a stemless glass and place the open end against the wall. Any sound waves that permeate the wall will resonate inside the glass and your ear will better be able to capture and process them.2015-08-01
How can I hear my neighbors through walls?
The sound transfer occurs as a result of airborne noise (voices, music, etc). The airborne sound wave strikes the wall and the pressure variations cause the wall to vibrate. This vibrational energy is transferred through the wall and radiated as airborne sound on the other side.2017-10-04
