摘要
A hearing aid (1) adapted for operation in a sound amplification mode and for operation in an occlusion measurement mode, has a microphone (10) adapted for transforming an acoustic sound level external to a hearing aid users ear canal (4) into a first electrical signal which is guided to an A/D converter forming a first digitized electrical signal. The hearing aid has signal processing means with a filter bank (41, 42) with means for splitting an electrical signal into frequency bands, and a receiver (20) adapted for generating acoustic sounds in the ear canal of a user when in said amplification mode, and for transforming the acoustic sound level in the ear canal into a second electrical signal, when in occlusion measurement mode. The invention also provides a system and a method for measuring the occlusion effect.
