Abstract
An assembly and a method for determining the distance between two sound providers, such as the ear pieces of a headset or two hearing aids. A signal is fed to the sound providers from a portable element, such as a mobile telephone, from a position to the side of the person, and from the travelling time of the signal, the distance is determined. Subsequently, audio signals taking the distance into account are fed to the sound generators.
Claims14
A method of determining a distance between two sound generating objects, the method comprising the steps of:
- positioning a signal provider at a position where the distance from the signal provider to the first and second objects are different,
- providing a first signal from one of a first of the objects and the signal provider to the other of the first of the objects and the signal provider,
- providing a second signal from one of a second of the objects and the signal provider to the other of the second of the objects and the signal provider,
- on the basis of the first and second signals, determining information relating to a distance between the first and second objects, and
- the signal provider accessing a first audio signal and generating a second audio signal by altering the first audio signal on the basis of the determined information and forwarding the second audio signal to the signal generating objects outputting a sound which is based on the determined information.
An assembly comprising a signal provider, a processor and two sound generating objects, wherein:
- the signal provider is configured to obtain a first audio signal and transmit a second audio signal to the first and second objects,
- the signal provider is configured to output an additional signal to the first and second objects,
- the first and second objects are configured to receive the second audio signal and feed a third audio signal to sound generators thereof,
- the first and second objects are each configured to receive the additional signal and output a corresponding signal, and
- the processor is configured to receive the corresponding signals and derive information relating to a distance between the first and second objects,
- the signal provider being configured to convert the first audio signal into the second audio signal on the basis of the derived information.
An assembly comprising a signal generator, a processor and two sound generating objects, wherein:
- the signal provider is configured to obtain a first audio signal and transmit a second audio signal to the first and second objects,
- the first object is configured to output a first signal to the signal provider,
- the second object is configured to output a second signal to the signal provider,
- the first and second objects are configured to receive the second audio signal and feed a third audio signal to signal generators thereof,
- the signal provider is configured to receive the first and second signals and output a corresponding signal, and
- the processor is configured to receive the corresponding signals and derive information relating to a distance between the first and second objects,
- the signal provider being configured to convert the first audio signal into the second audio signal on the basis of the derived information.
