    • 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.
    • 本发明涉及一种助听器,其具有至少一个主要声音以电转换换能器将环境中的声音转换为电信号;以及信号处理单元,用于根据用户的需要放大电信号,以及电 - 声换能器,用于接收 放大的电信号并将声音信号传送到耳朵,其中提供至少一个另外的声音到电传感器。 所述另外的传感器对风噪声的灵敏度小于主要传感器的风噪声的灵敏度,此外,信号处理单元具有用于检测从主声音到电转换换能器的信号中的风噪声水平的装置。 根据本发明,还提供了选择装置,用于从主或至少一个另外的声音到电变换器中选择要放大的信号。
