Alarm Sound Acquisition and Analysis

Industry: Medical

Applications: SVQ Target Development

Alarm sounds in the medical industry must be easily detectable and recognizable so that an immediate and appropriate course of action may be taken by caregivers in the event of an alarm sounding. A medical technology supplier approached Sound Answers to perform a study of existing medical alarm sounds so that they could develop an alarm sound for a new product. Sound Answers measured alarm sounds on-site at three hospital locations using both a Binaural Head and Torso Simulator and a handheld SPL meter. These sounds were collectively analyzed to gain an understanding of their time and frequency domain contents, and also what potential opportunities exist for new alarm sounds.
