Abstract
Abstract Programmable signal processing device mainly intended for hearing aids and of the kind which includes an electronically controlled signal processor, the device being able to select a number of different signal processes to suit different sound situations automatically or by the user himself. This is accomplished by a memory (6) arranged to store information data for at least two unique signal processes adjusted to different sound environment/listening situations and a control unit (5), manual or automatic, arranged to transmit information data for one of the unique signal processes from the memory (6) to the signal processor (4) to bring about one signal process adjusted to a particular sound environment/listening situation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
Programmable signal processing device (1), mainly intended for persons having impaired hearing, and of the kind which process an input signal containing information such as speech or music and which includes an electronically controlled signal processor (4) characterized in that a memory (6) is arranged to store information/data for at least two unique signal processes adjusted to different sound environments/listening situations and that a control unit (5) manual or automatic is arranged to transmit information/data, for one of the unique signal processes, from the memory (6) to the signal processor (4), to bring about one signal process adjusted to a particular sound environment/listening situation.
Claim 2
Dependent Claim
104 words
Programmable signal processing device (1), mainly intended for persons having impaired hearing, and of the kind which process an input signal containing information such as speech or music and which includes an electronically controlled signal processor (4) characterized in that a memory (6) is arranged to store information/data for at least two unique signal processes adjusted to different sound environments/listening situations and that a control unit (5) manual or automatic is arranged to transmit information/data, for one of the unique signal processes, from the memory (6) to the signal processor (4), to bring about one signal process adjusted to a particular sound environment/listening situation.
Claim 3
Dependent Claim
45 words
Programmable signal processing device (1) according to claim 1, characterized in that a control gear (9) is arranged to influence the control unit (5), manually, thus that digital information is transmitted from the memory (6) to the signal processor (4) for specifying the signal process.
Claim 4
Dependent Claim
52 words
Programmable signal processing device (1) according to claim 1 or 2, characterized in that the signal processor (4) is arranged to influence the control unit (5) automatically, depending on the sound environment, thus that digital information is transmitted from the memory (6) to the signal processor (4) for specifying the signal process.
Claim 5
Dependent Claim
57 words
Programmable signal processing device (1) according to one or more of the preceding claims, characterized in that a programming unit (2) is connectable to an input/-output terminal (3) of the signal processing device (1) and arranged to influence the control unit (5) thus that digital information is transmitted between the programming unit (21) and the memory (6).
Claim 6
Dependent Claim
67 words
Programmable signal processing device (1) according to one or more of the preceding claims, characterized in that two attenuators (18a, 18b) and one switch (20a) are connected to input terminals of a summing amplifier (22a) and are arranged to balance and adjust the signal levels supplied to inputterminals (3, 10, 11) of the signal processing device (1) from different signal sources, to the actual sound environment/listening situation.
