In episode 99, the Chimera Ant bat says, "Water significantly weakens the
power of sound!"

[!["Water significantly weakens the power of
sound!"](https://i.stack.imgur.com/aEkCH.jpg)](https://i.stack.imgur.com/aEkCH.jpg)

But water [is a good conductor of
sound](http://www.answers.com/Q/Why_is_water_a_good_conductor_of_sound). Why
does she say this?

Why does the Chimera Ant bat suggest that water weakens sound?


Because water is more dense than the air, the sound does travel faster through
water, i think about 4 times faster than air! but because water is dense it
also needs more energy to moves the water particles ! which is why you can
hear a faint sound in air but in water it doesn't even start, so you can't
hear anything  
in the end what you read in the link you mentioned is a talk about sound
speed, which is indeed faster in water, and even faster in metal ! but there
are variables such as initial energy needed for moving the particles, so you
can hear  
This site too, explains about sound travel under water

She probably says this because water weakens the effect of the technique,
[secret sound](http://hunterxhunter.wikia.com/wiki/Bat), that Bat.

In this scene, Gon rips a bit of his trouser pocket before making them damp
with saliva and stuffing them in his ears, effectively making earplugs for
himself.

Practically speaking, fabric itself doesn't make good earplugs, but by
dampening it, it works quite well.

If Bat's sound waves cannot be heard as well, it won't have the same effect.
Therefore it is weaker.

It's important to note that the original phrase was: 水は音波のエネルギーを著しく弱める

Which can be translated, taking in context, to: Water significantly weakens
the energy of the sound wave.

Therefore it could be her referring to how water is weakening the effect of
her technique, instead of sound in general.
