Heliox
Heliox is a diving breathing gas, consisting of oxygen and helium, that is often used during the deep phase of dives carried out using technical diving techniques.
It is a more expensive gas than its close rival Trimix and is more often used in commercial diving.
As sound travels faster in heliox than in air, voice formants are raised, making divers' speech incomprehensible to people not used to it.
