Sound event detecting apparatus and operation method thereof

An acoustic event detecting apparatus comprising:

• a receiver configured to receive an acoustic input;
• a sound processor configured to extract frequency characteristics of the acoustic input and determine whether a first acoustic event has occurred by analyzing the extracted frequency characteristics;
• a data acquirer configured to acquire at least one of an image and a video from an environment outside of the acoustic event detecting apparatus, in response to determining that the first acoustic event has occurred;
• and
• a communicator configured to transmit the acquired at least one of the image and the video to a first device,
• wherein the first acoustic event is an event in which a sound is generated, and is classified by at least one of a type of sound source generating the sound and a characteristic of the generated sound, and
• wherein the sound processor is further configured to operate in a multi-acoustic event detection (multi-AED) mode or a simple acoustic event detection (simple-AED) mode based on whether the environment outside of the acoustic event detecting apparatus is an environment where overlapping acoustic events occur.
