Acoustic Signals

Acoustic signals are vibrations in the air that can be heard by the human ear. They carry information such as musical sounds, speech, and other audio data. Acoustic signals are critical in communication, entertainment, and learning. They are used in sound-producing devices like loudspeakers and headphones, and by biomedical engineering technologies like stethoscopes, blood pressure monitors, and hearing aids. They help us to identify and respond to potential threats, such as fire alarms and car horns. Furthermore, acoustic signals are used for machine learning applications, to help robots and computers understand and interpret the world around them.
