Abstract
A binaural hearing device system comprises a reception device (1) for one ear with at least two input acoustical/electrical converters (3a, 3b). Via a communication link (5) a signal (A1) which depends on both input converter's output signals is transmitted to a second device (7) for the other ear which comprises at least an output electrical/mechanical converter.
Claims18
A method for producing a hearable signal to an individual comprising:
- first sensing acoustical signals impinging at one of individual's ears;
- second sensing acoustical signals impinging at the other of individual's ears;
- generating at one of individual's ears a signal to be perceived by the individual in dependency of the results of said first and second sensings;
- said dependency including
- a first dependency from the result of said first sensing weighed by a first weighing factor, and
- a second dependency from the result of said second sensing weighed by a second weighing factor,
- said first and second weighing factors being each controllably variable independently from the other;
- and
- generating at the other of individual's ears a signal to be perceived by the individual in a further dependency of the results of said sensings,
- said further dependency including
- a third dependency from the result of said first sensing weighed by a third weighing factor, and
- a fourth dependency from the result of said second sensing weighed by a second weighing factor, wherein
- said first, second, third and fourth weighing factors are each controllable variable independently from the others.
