For high powered aids the tubing should be thick-walled with a hole diameter of 2mm. Use of standard tubing on high powered aids may cause feedback. Earmoulds need to be re-tubed regularly. Replace the earmould tubing as soon as it begins to harden. It is surprising how much the tubing can affect the sound quality. Girls, welcome to the Still shine.th shop!
