Sound in a reef aquarium?

My tank used to be next to this ….. never any issues.

If you've ever been diving down on a reef you'll notice that the wild is pretty noisy too sometimes!

Two thoughts taken from us navy studies on sonar and its effect on wildlife.

Avoid 2kHz and 10 kHz frequencies directed towards the tank itself. Let the speaker bounce off walls then enter the tank, dont point the speakers at the tank. This is actually outside the range you can understand langauge, no idea how much a home speaker produces at these frequencies.

And avoid high intensity sounds(this one is more difficult to determine tbh). As this is a measure of the amount of energy carried by the sound. Which is not directly related to its decibel.

Plenty actually.

Very.

Are them bass boxes built into the wall beside the towers?

Loud sounds do make my whites tree frogs croak.

Omg I never knew that. That's cool to know.

Sometimes there are hidden gems of knowledge gleaned from threads on the internet

Indeed, though as my hearing has declined over time expensive audio equipment upgrades have been replaced by silly fish and coral purchases. Those speakers were bought in 1995 .... and the manufaturer is long out of business so spare parts are problematic.

No. I was really into high end audio a while back, and educated myself in the arcane arts of audio wave propagation within a fixed space ..... so they’re sound absorbing panels to improve audio coherence ...... yada yada.

Fully understand. I used to be into audio although not to what you are showing there. My mother used to work for a older speaker company ESS and I met Dr. Oscar Heil who designed the Heil Diaphragm. I carried around a set of AMT loud speakers for many a year and only recently retiring them when I ran out of the original diaphragms. The only drawback is that they really needed a large room to get the full effect.

That’s cool. I remember AMT speakers with the big Heil tweeter. Mine pictured use planar magnetic/ribbon transducers for mids and highs; then a boatload of good old piston cones for the bass.

Sorry for the rabbit hole OT ....
