Abstract: A sensor (1) for determining both a cadence of a crank and a travelling speed of a bicycle includes an accelerometer (4) providing a first signal dependent on a first acceleration along a first measurement axis (z) and a second signal dependent on a second acceleration along a second measurement axis (y) perpendicular to the first measurement axis. The accelerometer (4), a wireless transmitter (6) and a power source (8) are contained in a housing (2) that can be attached to a wheel of the bicycle. The sensor (1) determines the cadence from the rate at which consecutive changes of polarity occur in the first signal, or from the rate at which consecutive positive and negative extreme values occur in the first signal. The sensor also determines the travelling speed from the rate at which consecutive maximum and minimum extreme values occur in the second signal.

Abstract: In a digital hearing aid device (1) frequency modification is employed above a lower spectral bound and in accordance with a compression factor. The frequency modification is dynamically adjusted in dependence on a sound environment analysis (10) or an end-user input (30), by modifying the frequency modification parameters such as a lower spectral bound and a compression factor. The adjustment can be based on an interpolation between predefined parameters. In certain sound environments, such as loud noise, own-voice and telephone conversations, frequency modification is reduced or switched off. The proposed solutions have the advantage that the occurrence of disturbing noise and of distortions of harmonic relationships at the end-user's ear is reduced and signal processing resources as well as battery resources are saved.
