A notification system includes: detection means (110) for detecting an acoustic event from voice data transmitted from a communication terminal held by a target person; and notification means (120) for sending a predetermined notification when the detection means (110) has detected the acoustic event. Accordingly, it is possible to determine the state of a target person regardless of the state of this person. Further, when the difference between an acoustic pattern of the voice data transmitted from the communication terminal and acoustic patterns registered in advance is outside a predetermined range, a management server (101) does not send a notification, whereby it is possible to prevent communication traffic from being increased based on unnecessary notifications.

A volume adjustment method comprising performing analysis on the collected sound signal surrounding a user terminal, to obtain composition information, where the composition information includes sound types included in the sound signal and proportions of sounds of the various types, and the sound types include blank sound, human sound, and noise, determining a current scene mode of the user terminal according to the composition information, and adjusting volume of the user terminal according to the determined scene mode.

A volume adjustment method and apparatus, and a terminal is presented. Perform analysis on the collected sound signal surrounding a user terminal, to obtain composition information, where the composition information includes sound types included in the sound signal and proportions of sounds of the various types, and the sound types include blank sound, human sound, and noise; determine a current scene mode of the user terminal according to the composition information; and adjust volume of the user terminal according to the determined scene mode, thereby significantly reducing occurrence of a case, caused by mistaken determining of the scenario, in which play volume adjustment does not conform to the scenario, and enhancing user experience.

A method includes recording, at an electronic device utilizing a microphone of the electronic device, ambient noise of an environment the electronic device is disposed in; electronically analyzing, utilizing one or more processors, the recorded ambient noise of the environment to determine one or more frequency bands to avoid; dynamically adapting, based on the electronic analysis, an auditory alert to be played at the electronic device, such adaptation including frequency equalization adjustments based on the determination of one or more frequency bands to avoid; and playing, at the electronic device utilizing one or more speakers of the electronic device, the adapted auditory alert.

The present invention discloses an system configured to distributed an behavior state signal to an subscriber terminal when the subscriber comes within an predetermine region of the environment. The system comprises of an plurality of A/V recording and communication apparatus arranging at an predetermine region of the environment, an behavior state processing unit configured to obtain and distribute data to and from components of the system, subscriber terminal and the one or more VSIM severs of the terminal service provider. The service provider further comprises an VSIM server configured to distribute one or more behavior state signals to the one or more subscriber terminals.

A notification system includes: detection means (110) for detecting an acoustic event from voice data transmitted from a communication terminal held by a target person; and notification means (120) for sending a predetermined notification when the detection means (110) has detected the acoustic event. Accordingly, it is possible to determine the state of a target person regardless of the state of this person. Further, when the difference between an acoustic pattern of the voice data transmitted from the communication terminal and acoustic patterns registered in advance is outside a predetermined range, a management server (101) does not send a notification, whereby it is possible to prevent communication traffic from being increased based on unnecessary notifications.

A method for generating adaptive notifications include analyzing, at a user device, a spectrum of environmental noise. A portion of the spectrum for adaptive notification enhancement is selected based on the analyzing the spectrum of environmental noise. An adapted notification is generated at the user device by enhancing the selected portion of the spectrum. The adapted notification is transmitted at the user device.

A mobile communication apparatus, an accessory device, and a method for adjusting one physical property of an acoustic signal, wherein the apparatus includes a ringtone generator adapted to generate the acoustic signal, an ultrasound receiver apt to receive an ultrasonic signal, and a processor configured for detecting at least a physical parameter and/or a content of the ultrasonic signal, determining, on the basis of the at least one physical parameter and/or content of the ultrasonic signal, attenuation information that can quantify the attenuation suffered by the ultrasonic signal and/or the acoustic signal, determining, on the basis of the attenuation information, the physical property of the acoustic signal to be generated, and generating the acoustic signal having the determined property, so that the probability to hear the acoustic signal increases.
