Audio monitoring system and method of use

摘要

A method includes receiving audible sound signals such as the cries of a baby via a microphone of a monitor, and processing the signals to identify whether a predetermined acoustic signature is present. An alert may be generated when the predetermined acoustic signature is present. An information data signal such as a discrete data packet quantifies how closely the sounds match the predetermined signature, and is transmitted to a remote device. The server may aggregate these data packets over time and calculate a variance between the aggregated data packets and a baseline. A report may be generated describing the sound signals and variance. A monitoring system having the monitor and a server are also disclosed.

1. A method comprising:
receiving sound signals via a microphone of a monitor; processing the received sound signals using the monitor, including dividing each second of the received sound signals into a plurality of equal time segments or frames and identifying, for each frame independently of the other frames, whether a predetermined acoustic signature is present in the received sound signals; generating, via the monitor, an information data signal in the form of a plurality of discrete data packets each of which quantifies how closely the received sound signals of a respective one of the frames match a predetermined acoustic signature over a calibrated interval, wherein each of the discrete data packets includes a plurality of descriptive data fields describing the received sound signals; transmitting the information data signal from the monitor to a remote device; receiving the transmitted information data signal via the remote device; selectively generating an alert via the remote device when a calculated rolling average or percentage of the frames match the predetermined acoustic signature over the calibrated interval.
