Abstract

An embodiment detects, using a sensor installed within a building, a first position of a first noise source. The embodiment generates a first noise control configuration comprising a first directional acoustic loudspeaker and a first frequency and first amplitude of a first acoustic tone, the first frequency and first amplitude of the first acoustic tone, when generated by the first directional acoustic loudspeaker, selected to attenuate the first noise source at a first distance from the first position. The embodiment generates, according to the first noise control configuration, the first acoustic tone.

First claim

What is claimed is:

1 . A computer-implemented method comprising:
detecting, using a sensor installed within a building, a first position of a first noise source; generating a first noise control configuration comprising a first directional acoustic loudspeaker and a first frequency and first amplitude of a first acoustic tone, the first frequency and first amplitude of the first acoustic tone, when generated by the first directional acoustic loudspeaker, selected to attenuate the first noise source at a first distance from the first position; and generating, according to the first noise control configuration, the first acoustic tone.

2 . The computer-implemented method of claim 1 , wherein the first noise control configuration comprises a conference area enclosed by a sound wall, the sound wall formed using a line of directional acoustic loudspeakers including the first directional acoustic loudspeaker, the line of directional acoustic loudspeakers selected from a set of directional acoustic loudspeakers installed within the building.

3 . The computer-implemented method of claim 2 , further comprising:
detecting, using a microphone, audio within a first portion of the conference area; and transmitting, using a first directional ultrasonic loudspeaker, the audio to a second portion of the conference area.

4 . The computer-implemented method of claim 3 , further comprising:
translating, using a trained machine translation model, the audio to a second language, the translating resulting in translated audio; and transmitting, using a second directional ultrasonic loudspeaker, the translated audio to a third portion of the conference area.

5 . The computer-implemented method of claim 1 , wherein the first noise control configuration comprises a noise attenuation area within a sound footprint of the first directional acoustic loudspeaker.

6 . The computer-implemented method of claim 1 , further comprising:
detecting, using the sensor, that the first noise source has moved to a second position; generating, responsive to the detecting, a second noise control configuration comprising a second directional acoustic loudspeaker and a second frequency and second amplitude of a second acoustic tone, the second frequency and second amplitude of the second acoustic tone, when generated by the second directional acoustic loudspeaker, selected to attenuate the first noise source at a second distance from the second position; and generating, according to the second noise control configuration, the second acoustic tone.

7 . The computer-implemented method of claim 1 , further comprising:
detecting, using the sensor, that the first noise source has altered by more than a specified amount, the altering resulting in a second noise source at the first position; generating, responsive to the detecting, a third noise control configuration comprising the first directional acoustic loudspeaker and a third frequency and third amplitude of a third acoustic tone, the third frequency and third amplitude of the third acoustic tone, when generated by the first directional acoustic loudspeaker, selected to attenuate the second noise source at a third distance from the first position; and generating, according to the third noise control configuration, the third acoustic tone.

8 . A computer program product comprising one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions executable by a processor to cause the processor to perform operations comprising:
detecting, using a sensor installed within a building, a first position of a first noise source; generating a first noise control configuration comprising a first directional acoustic loudspeaker and a first frequency and first amplitude of a first acoustic tone, the first frequency and first amplitude of the first acoustic tone, when generated by the first directional acoustic loudspeaker, selected to attenuate the first noise source at a first distance from the first position; and generating, according to the first noise control configuration, the first acoustic tone.

10 . The computer program product of claim 8 , wherein the stored program instructions are stored in a computer readable storage device in a server data processing system, and wherein the stored program instructions are downloaded in response to a request over a network to a remote data processing system for use in a computer readable storage device associated with the remote data processing system, further comprising:
program instructions to meter use of the program instructions associated with the request; and program instructions to generate an invoice based on the metered use.

11 . The computer program product of claim 8 , wherein the first noise control configuration comprises a conference area enclosed by a sound wall, the sound wall formed using a line of directional acoustic loudspeakers including the first directional acoustic loudspeaker, the line of directional acoustic loudspeakers selected from a set of directional acoustic loudspeakers installed within the building.
