Just caller’s voice mobile, no back sounds

Lets other hear only your voice no background sounds and disturbances

My technique, a simple augmentation inbuilt in your mobile will solve the problem, please read the following:

Problem:

You call someone while you are at a noisy place; the other person hears all sorts of back sounds and thus disturbs the conversation. Loud-speaker, TV, traffic honking, railway, people talking around you disturbs the conversation if you call someone. The person can’t hear properly. This could be dealt with a unique augmented mobile.

Result:

A mobile phone which recognizes only the caller’s voice and eliminates all other surrounding sounds while the call is made. The person who receives the call hears just the caller voice and no other sounds, even though the caller is at a very noisy place.

Two tier

If even the receiver is having same version mobile, the two persons conversing will hear just the other person, and conversation would become convenient, disturbance free conversation.

Theory:

Every source of voice emits sounds with a frequency. These sounds are received by receiver (observer). There is some distance between the source and observer of the sounds.

Doppler’s effect states that sound frequency changes as the distance between source and observer changes.

My technique/ solution:

The receiver set in mobile receives sounds from different sources, the mouth of person who speaks (10-15 cm), from other people at least (24 cm up to few metre), nearby TV or speaker sets (5 to 6 metre), vehicle passing by ( 2 to 12 metre and more) this can go to as many sources as possible. It is obvious sounds reaching from various sources have different frequencies and are definitely different from the frequency of sound which is originating from the mouth of the person who is speaking. Thus there are two groups of sound one from the person who is speaking on the mobile (unique frequency) and other sources (several frequencies).

An inbuilt frequency sensor is the answer, it recognizes the source whose sound is to be transmitted (the caller’s mouth) the distance is about 10 to 15 cm, after recognizing the source it reads the frequency of the sound and start to isolate this particular voice (unique source and unique frequency) of the caller and begins to transmit only this sound. All other sound waves having different frequency and source points other than caller’s mouth would be eliminated from further transmission. This would result the person who receives the call to hear only the voice of person who has made the call, all sounds around the caller are eliminated and the receiver can’t hear anything other than the voice of the person who is speaking.

If both the persons, one who made the call and the person who receives the call are having the same version (inbuilt frequency sensor) mobile phone they would hear only the voice of person who speaks and not the surrounding sounds.

Illustration:

In illustration 1 the mobile of person who made the call is receiving all sorts of sounds, sounds from caller’s mouth (cyan colour), sounds from the bus behind (red colour) and sounds from nearby loud speaker (dark blue sound). It transmits all sound combined to the person receiving the call. See in illustration 2 the person who received the call hears all sounds, sounds of person speaking (cyan colour), sounds of Bus (red colour) and sounds of loud speakers (dark blue colour), resulting in a disturbed inconvenient conversation.

In illustration 3 same things happen as in 1, the mobile of person who made the call is receiving all sorts of sounds, sounds from caller’s mouth (cyan colour), sounds from the bus behind (red colour) and sounds from nearby loud speaker (dark blue sound). But it transmits only the sounds of person speaking (cyan colour) and eliminates all other sounds, because of inbuilt frequency sensor, resulting in a disturbance free, convenient conversation.

Certain consideration and exceptions

Off course the voice of the person who is speaking may have variable frequencies too but the source in this context is same, also the frequencies would remain within the band. Which is what sensor recognizes.

Secondly, there may be a sound from surrounding which may have the same frequency in this case the source is definitely away, and there are low chances of such sound which matches the frequency. Even if there be this case the altogether total sound disturbance is definitively low compared to mobile which won’t be having inbuilt voice sensors.
