The most effective way for hotels to listen to spring.

Help you find two ways to listen to the hotel spring sound:

Method 1: use the paper cup provided by the hotel, dig a small hole in the bottom, and then stick the opening of the cup on the wall, with your ear close to the small hole.

Method 2: Use a cheap hotel room with poor sound insulation, close the doors and windows, close the curtains, and put an aquarium in the room, because the material of the aquarium can play a role in sound insulation, so you can clearly hear the sound of spring.

It should be noted that hearing the sound of spring may affect your sleep quality. I suggest you make sure that you can get enough rest before using the above methods.
