The invention discloses an alarming method and an alarming
system according to
sound sources. In the invention, by pre-recording a first sound source, the acoustic parameters of the first sound source under the condition of needing alarming are determined; by pre-recording a
second sound source in real time, the acoustic parameters of the
second sound source are determined; and the acoustic parameters of the first sound source and the acoustic parameters of the
second sound source are compared respectively. When two or more acoustic parameters of the second sound source exceed alarming threshold values of the acoustic parameters and the
duration time of the second sound source achieves a
duration time alarming threshold value of the second sound source, an alarm is sent out. The method and the
system can discover the abnormal condition of a user in the first place and timely make solutions, thus preventing the family of the user from suffering from irreparable damage; and the method and the
system solve the technical problems that due to no
noise when the user safety is ensured by
video monitoring, in order to know the
safety condition of the user, security personnel needs to keepa close watch on a displayer indispensably, so that when the security personnel discovers that the user has an accident or losses things, a period of time passes already and an optimal rescue opportunity is missed.
