Abstract

Microphone arrays comprise several microphone capsules, the outputs of which being electronically combined for directional recording of sound. The directional and frequency properties of the microphone array depend on the number and positions of the microphone array. In order to obtain the smallest possible microphone array with only few microphone capsules, which, however, has an essentially uniform directional and frequency dependence over a speech frequency range, is scalable and robust against small incorrect positioning of the capsules, fifteen or twenty-one microphone capsules (K15,11 - K15,35, K21,11 - K21,37) are arranged on a carrier such that they lie on three similar branches, each with the same number of microphone capsules, which are rotated against each other by 120°. Each of the microphone capsules lies on a corner of a triangle of a grid in a flat isometric coordinate system with three axes rotated by 60° against each other and forming the grid_of equilateral triangles.

Abstract

A method for automatically controlling loudness of an audio signal to be replayed within a vehicle is provided. The method comprises an automatic loudness measurer measuring a loudness of an incoming audio signal that comprises a sequence of digital audio blocks. Furthermore, a noise level indication signal is received which indicates a noise level within the vehicle and a processor calculates a gain factor based on the measured loudness of the incoming audio signal and the noise level indication signal. If the measured loudness is equal to or above a predefined first target loudness (TLamS), the gain factor is zero. Otherwise, if the noise level indication signal indicates a noise level equal to or above a predefined intermediate noise level, the gain factor is a difference between the measured loudness and a current target loudness, limited to a maximum gain, wherein the maximum gain is a defined absolute maximum gain, and the current target loudness is linearly interpolated, according to the noise level indication signal, between a predefined second target loudness (TLaiS) for the noise level being equal to said intermediate noise level and the predefined first target loudness (TLamS) for the noise level being equal to a predefined maximum noise level. Otherwise, if the noise level indication signal indicates a noise level below the intermediate noise level, the gain is linearly interpolated, according to the noise level, between the gain as defined for the intermediate noise level and zero. Furthermore, the gain factor is applied to the audio signal to be replayed.

Abstract

When an OFDM radio system which uses a wide frequency band is interfered with by another narrow-band radio system, the interference can frequently be compensated but the transmission quality decreases drastically. Thus, narrow-band interferers in an OFDM radio system are determined according to the invention whereby none of the subscribers of the radio system transmits in a defined time slot or scan slot but all switch at the same time into the receiving mode. If there is interference (P1, P2), it is detected in this time slot. Countermeasures are taken individually in all the mobile devices, in particular the detection of the frequency and strength of the narrowband interference (P1, P2) and the configuration of a flexible notch filter (140) in the time range to the detected frequency and strength. The scanned received signal (RXS) is then filtered in the time range, i.e. before the FFT (120) and the OFDM channel estimation (130) by the correspondingly configured notch filter (140). The notch (S1, S2) of the notch filter thereby acts in the transmission function like a natural break when receiving data.

By way of the credentials the mobile radio operator can allow the local end user limited usage of that radio spectrum range in fee-bearing fashion and can bill same. The local user can then use the assigned frequency band in accordance with his own needs. In particular the user can wirelessly transmit signals in the assigned frequency range between end devices to which no credentials are allocated and in that situation use a transmission protocol which is not defined for the mobile radio network.

Abstract

To secure earphones in the auditory canal of a user, ear tips are used. In an improved earphone (200), which reduces or avoids pressure sores occurring in the ear of the user, a hard stub of the housing no longer protrudes as hitherto into the ear tip, and instead a soft receiving tube (220) of the ear tip is secured in the housing (250). By means of this inverse receiving principle, the ear tip can better conform to the auditory canal and thus enhances the wearing comfort. For assembly, the tube (220) is plugged into an opening (245) in the housing so that a projection (225) of the tube engages in a depression or inner shoulder (245a) behind the opening and thus secures the ear cushion on the housing.

Abstract

Microphone capsules for condenser or electret microphones often exhibit individual deviations from a desired ideal behavior, e.g. the frequency response and phase response. Particularly if a plurality of microphone capsules are interconnected to form a microphone array, suitable microphone capsules must be found in a selection process. Some of these deviations can be corrected electronically, e.g. by filtering with a corresponding filter that is individually adapted. An improved microphone capsule, with which an automatic selection and automatic assembly of circuit boards with microphone capsules is facilitated, comprises an electrostatic sound transducer, an amplifier element that outputs an amplified output signal of the electrostatic sound transducer, and at least one electronic memory element. Data obtained by a measurement and relating to the individual frequency response or phase response of the respective microphone capsule can be stored therein. The data can be read out during manufacturing and during operation, which enables automatic sorting of the capsules during production and automatic calibration of the target circuit in operation.

Abstract

Power supply units e.g. in network operated loudspeakers are tailored to peak values that are reached only relatively rarely and then in pulses. With an intermediate storage of electrical energy in an intermediate circuit energy storage element it is possible to provide a significantly higher amount of power at least for a short period of time. The intermediate circuit energy storage element may be a capacitor or accumulator, for example, which is connected to an intermediate circuit voltage that is higher than the input voltage, and that is generated by an upconverter. A downconverter generates the output voltage of the power supply unit from the energy stored in the intermediate circuit storage element. The output voltage of the power supply unit is used as power supply for an audio amplifier. The power supply unit may provide for a short period of time a higher current or more energy respectively than the actual energy source, for example the network node. Correspondingly, the device operated with the output voltage of the power supply unit, for example the audio amplifier, can have a significantly higher effective power than previously possible for the short period of time.

Abstract

In radio networks having a plurality of access points, for example WiFi, a wireless audio end device like for example a microphone or headphones is connected to an access point, to which it sends its audio data or from which it receives same. Audio transmission should occur as far as possible in interruption-free manner and with low latency. If the audio end device is moved the connection quality in relation to the previous access point can decrease and require scanning or roaming. In that respect first another base station is sought and then the radio connection is redirected there. In order in that case to avoid disruptive signal interruptions portions of the audio signal which can be particularly well predicted are detected or predicted by means of short-term statistical methods, like for example speech pauses. Scanning and roaming are then carried out during the predicted portions, whereby interruptions which are perceptible to a user are avoided.

Abstract

For mobile devices used in a wireless audio transmission system, for example for stage technology, like wireless microphones, body-pack transmitters with an audio input, and body-pack receivers with an audio output, electronic displays are known, on which a respective radio frequency or radio channel in use or other alphanumeric information is displayed. This information can be input at the transmitting end, for example, at a central location like a mixing desk. The displays, however, only function while the mobile devices are switched on so that it is not possible to see the association(s) of the mobile device(s) in their switched-off state. For improved identification of wireless microphones, body-pack transmitters, or body-pack receivers in which an automatic alphanumeric identification of the transmission channel in use is displayed in the switched-on state, according to the invention the display of the identification is retained even after the microphone, body-pack transmitter or body-pack receiver is switched off. In this way, mobile devices can be associated with a radio transmission path, an artist or a stage position even in the switched-off state.

Abstract

There is set forth a method and a system for recording and synchronizing audio and video signals. The audio signal and the video signal are stored together with time stamps from a respective associated system clock. The invention relates to an adaptation of the duration of the recorded audio sequence to the duration of an associated video sequence in order to level out differences in synchronization of the two system clocks. Alignment of the two system clocks is also introduced, which is based on a data transfer which has variable waiting times for the access to a transmission channel.
