    • A mobile station (100) that includes a processor (212) that selectively disables at least one station component to reduce electromagnetic noise generated by the station in the frequency range below 20 kHz when the mobile station is operated in the hearing aid compatible mode. The component can be, for example, a display (204), a light (206) or a wireless interface (208). The processor also can optimize characteristics of audio signals transmitted from the mobile station to the hearing aid for reproduction by the hearing aid. For instance, the processor can selectively adjust filter parameters (216) and/or a signal gain (218) applied to audio signals. A user interface (220) having a soft-key can be provided to cycle through various HAC options.
    • 一种移动台(100),其包括处理器(212),当所述移动台在助听器兼容模式下操作时,所述处理器选择性地禁用至少一个站组件以减少所述站在20kHz以下的频率范围内产生的电磁噪声。 该组件可以是例如显示器(204),光(206)或无线接口(208)。 处理器还可以优化从移动台发送到助听器的音频信号的特性,以便由助听器再现。 例如,处理器可以选择性地调整应用于音频信号的滤波器参数(216)和/或信号增益(218)。 可以提供具有软键的用户界面(220)以循环通过各种HAC选项。
