Acoustic sensors are effective when the glass is positioned where?

Acoustic sensors are designed to detect sound waves, which makes their effectiveness highly dependent on how sound travels from its source to the sensor. When the glass is positioned in direct line of sight to the sensor, it enables the acoustic sensor to pick up the distinct sound patterns created when glass is broken. This direct line of sight reduces interference from obstacles that may absorb or distort sound waves, thereby enhancing detection accuracy.

Positioning the glass further away or obstructing the line of sight can diminish the sensors' ability to faithfully capture the sound event. This degradation happens because sound waves can get weaker and can be scattered or absorbed by materials in their path, making it harder for the acoustic sensor to function effectively. Therefore, for optimal performance, the glass should be positioned in direct line of sight of the acoustic sensor.
