Abstract
The invention concerns a hearing aid with at least one primary sound to electric converting transducer converting sounds in the environment into electrical signals and a signal processing unit for amplifying the electrical signal according to the needs of the user and an electrical to sound transducer for receiving the amplified electrical signal and delivering a sound signal to the ear wherein at least one further sound to electrical transducer is provided. The said further transducer has a sensitivity to wind noise which is smaller than the sensitivity to wind noise of the primary transducer and further the signal processing unit has means for detecting the level of wind noise in the signal from the primary sound to electric converting transducer. According to the invention also selecting means are provided for selecting the signal to be amplified from either the primary—or the at least one further sound to electrical transducer.
