What are Sound Sensors?

Sound sensors, also known as acoustic sensors or microphones in many applications, are devices that detect sound waves and convert them into electrical signals for processing. They operate based on principles like piezoelectric, capacitive, or electret technology to capture audio vibrations across various frequencies. Common types include hydrophones (for underwater detection), surface acoustic wave (SAW) sensors, and bulk acoustic wave (BAW) sensors. These sensors are integral to applications requiring noise monitoring, voice recognition, security surveillance, automotive safety systems, and industrial automation. In consumer electronics, they enable features like voice assistants; in healthcare, they support hearing aids and diagnostic tools; while in defense, they facilitate sonar and detection systems. Advancements focus on miniaturization, sensitivity, and integration with IoT for smart environments.
