When I lived in the US, I used to work in Terminal C at Logan. I could have sworn that the Legal Seafoods had a giant aquarium with fish swimming around in it.

Correct me if I'm wrong, but isn't water a great conductor for sound? Wouldn't the fish hear the aircraft outside much louder than us?

Or am I totally wrong?


... the thoughts that go through my head when I first wake up ...  Yeah sure

water is a good conductor of sound compared to air, or in other words is a better medium for propagation, which means that the speed of sound in water is faster than in air. So the fish will not here it louder but at the same intensity as we hear it.

Maybe, but they have a much shorter memory than us so they wouldn't remember they had heard it for very long....  wink

say what?  confused  have you ever tried to yell in a swimming pool? water is a TERRIBLE conductor of sound as compared to air......

water has density (the more the salinity, the greater the density), which prevents sound waves from propagating....where as air has basically no density..

Water is a much better conductor of sound than air but the sound waves in the fish tank cannot be greater than in the air surrounding the tank, so no, the fish wouldn't 'hear' the sound louder.

This is, of course, neglecting other factors, such as sensitivity of fish to sound, mode of detection of sound by fish (as far as I know, they 'feel' sound rather than 'hear' it), and transmissibility of sound by the glass tank itself, etc..

When my now-ex girlfriend and I were in AMS, we saw a few big tanks of fish. She, a zoologist, explained that fish are deemed to be relaxing, hence their presence.

Cork Airport used to have an ornemental fishtank in arrivals.

It may be gone now, as there is a lot of redevelopment there and some time since I visited.

The fish seemed as happy there as they do anywhere else - probably a lot happier than fish in any tank outside a fish restaurant anyhow.

The passengers are not so happy about the lack of jetways, in a rainy country you can get seriously wet even in a small airport.

The only fishtank I know of in AMS is in fact a Bombay Sapphire "advertising medium", i doubt that was put there as a relaxing element.

I saw four bigs tanks, full of live fish, when I was last at AMS (4x in June).

Another airport with fish is SRQ.

Quoting Jacobin777 (Reply 3):

Yeah, because human vocal cords, which are designed to make noise in air, can't make the same noise underwater, that must mean water can't conduct sound.

Ever tapped a watch on a handrail in the pool? Try it sometime. You can hear it all over the pool underwater. Above the water, you can barely hear it at the other end of the pool. Of course that also has something to do with the ambient noise of the air.

But, back on topic, water doesn't conduct sound from the air very well. Yelling above the surface would barely be heard below. As a swimmer, I know this quite well. You tend to only hear the cheers of a race when your head is above the water. As soon as you dip under, you only hear the sound of swimming, and faint other noises.

So, no, the airport noise does not likely disturb the fish. But kids tapping on the glass does.

Live fish must not mind it too much. America West used to carry live fish as cargo to pet stores here in Columbus. I remember unloading several dozen boxes of live fish off numerous A320s coming from LAX, PHX, and LAS while I was there. I think the only time they were really bothered was when they arrived in CMH during the winter.
