Computer-based methods for acoustic event recognition are developed at the Fraunhofer IDMT – from recognition of individual acoustic events through to analysis of complex scenarios. One application area is inpatient or home care: potentially dangerous situations such as breaking glass, frequent coughing or calls for help are acoustically recognised. As part of corresponding research projects, scientists investigate the potential solutions and methods that will allow use of acoustic data in networked buildings and cities for applications in the fields of security, traffic management and energy efficiency. Abnormal operating noises can also be detected acoustically, e.g. in vehicles, in status monitoring of machines or for acoustic end-of-line checks in industrial production.

In addition to the usual display of the light call in the duty room, SonicSentinel also displays additional information about the type of emergency. This optimizes the reaction times of the care staff and improves care quality.
