Title Method to Adjust Speaker Volume Based on Distance between Two Devices, Ambient Noise, and Conversation Abstract Disclosed are a method and system to combine the proximity, ambient noise qualities, and the detection of human speech to automatically produce the user’s optimum desired volume in a speaker system while in an open and changing space with multiple variables. Description Several factors can negatively affect the quality of the sound and the user’s overall experience (e.g., enjoyment, level of productivity, etc.) when listening to some audio (e.g., music) through a stereo system via speakers. These factors can include the listener’s distance away from the speaker, natural and mechanical noise in the environment, and the need to manually adjust speaker volume when engaging in and finishing a conversation. A system or method is needed to automatically adjust speaker output volume to account for impeding factors and provide the optimum user experience. The novel contribution is a method and system to combine the proximity, ambient noise qualities, and the detection of human speech to produce the user’s optimum desired volume in an open and changing space with multiple variables. Enabling art includes:
• The ability to detect and differentiate human speech audio levels
• The ability to detect ambient noise
• The ability to detect distance between objects
• Machine learning
The proposed system enables the listener to set the volume to the desired level using a remote device or a control affixed to the speaker. At the time the user sets the volume, the system assesses the original environment for the factors desired (e.g., distance from the remote device, ambient noise at both the speaker and the remote device, and presence of human speech), and records that as a baseline. The system identifies three factors to determine whether to automatically increase or decrease speaker volume:
• Proximity. The system determines proximity using a Global Positioning System (GPS) in both the speaker and the device. The speaker system checks the GPS coordinates of each device, detects changes in the distance between the two, and then using the difference between the devices’ original distance and the current distance to determine whether to automatically alter the volume.
• Level of ambient noise. With an open space, it is important to measure the ambient noise in the area at both devices’ locations, using the most current
methodology for doing so. The system uses the information about the ambient noise at both locations to determine the second factor as to whether to automatically alter the volume.
• Presence of human speech. The system detects the introduction human speech, which indicates that the user is engaged in a conversation. Active conversation automatically lowers the volume, and the end of a conversation automatically raises the volume.
The listener can set the priorities/weights of the factors and the degree of reaction to the factors. F...
