Handset Ringtone Calibration and Acoustic Location in Call Centers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In call centers, the indiscriminate ringing of multiple handsets causes confusion and discomfort, and locating a specific handset among many is difficult and time-consuming due to their close proximity.
Innovation Solution
A system utilizing VOIP software and handset microphones for automated calibration and location, adjusting volume levels and detecting sound signals to calibrate and locate handsets within a closed locality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple handsets are placed close together in a call center, then space utilization is improved, but locating a specific handset becomes difficult and time-consuming
Solution Approach 1:
The patent replaces the mechanical search method (technicians physically walking through rooms to locate handsets) with an acoustic field-based system. Each handset emits a unique acoustic signal that can be detected by microphones in other handsets, allowing automated identification and location of the target handset without physical search.
Solution Approach 2:
The patent introduces acoustic signals as an intermediary medium between handsets. Instead of direct visual or physical contact for location, handsets communicate their identity and position through acoustic emissions that propagate through the air, enabling indirect detection and localization of specific devices.
2Adaptability or versatility
If multiple handsets ring simultaneously in a call center, then communication capability is maintained, but noise interference and confusion increase
Solution Approach 1:
The patent segments the acoustic environment by assigning each handset a unique acoustic signature or code. This allows the system to distinguish between multiple simultaneous ringings, separating their signals in the acoustic domain so that individual handsets can be identified and located without interference from others.
Solution Approach 2:
The patent implements local quality differentiation by giving each handset a distinct acoustic characteristic. The acoustic signals are not uniform but tailored to each device, allowing the system to detect and differentiate local sources based on their unique acoustic fingerprints even when multiple handsets operate simultaneously.
Applied Scientific Principles

AI summary
A method that includes selecting a first handset from multiple handsets in a locality and instructing the first handset to generate a first ringtone is provided. The method also includes receiving a volume value of the first ringtone measured with a microphone, adjusting, in the first handset, a volume level for the first ringtone based on a desired volume level, and providing a notification to the first handset that the volume level of the first handset has been calibrated. A system and a non-transitory, computer-readable medium storing instructions to perform the above method are also included.
