Abstract: 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.

Abstract: A portable electronic device (100) includes a vibrating transducer having a resilient support and a first mass supported by the first resilient support forming a mechanical resonator, and an electrical circuit coupled to the first vibrating transducer to apply a drive signal. A plurality of tactile vibration transducers (130, 140) can work in unison to produce strong tactile stimulus (216, 228, 230).

Abstract: A system, method, and apparatus for separating speech signal from a noisy acoustic environment. The separation process may include directional filtering, blind source separation, and dual input spectral subtraction noise suppressor. The input channels may include two omnidirectional microphones whose output is processed using phase delay filtering to form speech and noise beamforms. Further, the beamforms may be frequency corrected. The omnidirectional microphones generate one channel that is substantially only noise, and another channel that is a combination of noise and speech. A blind source separation algorithm augments the directional separation through statistical techniques. The noise signal and speech signal are then used to set process characteristics at a dual input noise spectral subtraction suppressor (DINS) to efficiently reduce or eliminate the noise component. In this way, the noise is effectively removed from the combination signal to generate a good qualify speech signal.

Abstract: Disclosed are methods and devices for adapting a ringtone in accordance with ambient noise. In one embodiment a method includes processing an ambient noise signal to determine an ambient noise volume. When there is an incoming communication and it is determined that the ambient noise has a low ambient noise volume, a method can include generating a ringtone having a ringtone volume that is initially a low volume and increasing the ringtone volume over a predetermined period of time. A method can include applying a filter to the ringtone signal to increase a signal-to-noise ratio, the filter configured to increase an amplitude of a frequency that is not one of the predominant frequencies of the ambient noise and that the transducer is configured to output according to the transducer frequency response. In another embodiment, a second transducer may generate a ringtone output in addition to the first transducer.
