The ocean
is about to get
much louder.

An international standards body is finalizing plans for an underwater Internet of Things — a global network transmitting data through the water itself, using sound. At 160–250 decibels, around the clock, across every ocean.

This is what that means — for the whales, the reefs, the fish, and eventually us. Scroll, drag, listen.

◉ Record · 47.3°N 8.2°W Depth 0 m Ambient 82 dB
◉ 01 / Listen depth 250 m north atlantic

Turn the dial. Meet the network as a whale would.

Five acoustic nodes. Each pulses data through the water as pressure waves. Drag the decibel dial to hear and see what changes as the network scales up to its planned operational range.

Audio is a loose approximation — your speakers can't safely reproduce 250 dB underwater. Real exposure would be orders of magnitude more intense.

◉ 02 / Impact threshold model · idealised

At 140 dB, this is who's hurt.

Threshold of harm varies by species and signal. Each row shows the level at which meaningful disruption begins in the published literature. The bar fills red when the current level crosses the threshold.

Impact class
Species groups experiencing harm at the current network level. The proposed operational range is 160–250 dB, continuous.
◉ 03 / Range sound doesn't stop at the source

A single node reaches 5.0 km.
There will be thousands.

Sound travels farther and faster in water than in air. Every 6 dB roughly doubles the audible range. At network scale, there is nowhere in the open ocean that is quiet.

◉ 04 / Compare two futures

There is a quieter way to build the underwater internet.

Fiber-optic cables already carry almost every byte of the world's internet beneath the sea. Extending the pattern — rather than replacing it with sound — would protect marine life without sacrificing the goal.

Before the first node goes live,
the standard can still change.
