Pre-Formed Hearing Aid Tubing
Standard BTE hearing aids use a 12 – 13mm tube connected to a custom ear- mold that fills the ear canal and holds the tube in place. Replacement tubes not only look and feel better but they help a BTE hearing aid to fit better. Tubes should be replaced every 3 months to get the best from a BTE instrument. Cracked or yellowing tubing will cause feedback and consequent reduction in amplification.
Adults will almost certainly require size 13 tubing, these are available in extra thick, thick, and medium. These three sizes prevent crimping, stretching and most importantly sound feedback from the aids. Thicker tubing contains sound better and reduces feedback commonly caused by powerful hearing aids.
The purpose of the Horn effect is to provide greater amplification in the 2 – 6 KHz frequency range. Horn tubes are preformed tubes that have a specific flare manufactured into them. The size refers to inside diameter of the tube and the ear-mould end.
They are available with 3mm standard, and 3mm and 4mm with tube retention.
