Talk:Ear clearing

There is a lack of reference to voluntary opening of the eustachian tubes as a method of ear clearing. I append the following based on the article on French Wikipedia as a possible addition. Peter (Southwood) (talk): 17:33, 1 January 2010 (UTC)

Voluntary opening of the eustachian tubes
Voluntary opening of the tubes (French: béance tubaire volontaire (BTV) ) is a method of equalising or clearing the ears described by doctor Georges Delonca and used in scuba diving and freediving. It aims to rebalance the pressure between the external ear and middle ear. the subject must either exercise a voluntary control of the muscles opening the eustachian tubes, or move the jaw to open the tubes when necessary.

This is less easy to execute than the Valsalva maneuver, but the BTV is the gentlest method to clear the ears. However, not all divers can perform this manoeuvre. It may be necessary to engage in ear training exercises to re-educate the muscles to perform this manoeuvre.
