Pontoon Reprise: Ultrasonics​.​.​.

from Sounds of the Marina by David de la Haye



The first track of this short album, 'Underwater Pontoon: Like A Huge Creaking Ship', may sound fairly relaxing. But what you probably can't hear are the ultrasonic deterrent sounds being emitted by a mystery source.

This piece crossfades slowly between the original track and a slowed down version (quarter speed, 0.25%).

The beeps sound 'added' but I promise they are not. You can view them on the spectrum of the first track. Try it!

Imagine having this disturbing noise pumped into your neighbourhood.
