Abstract [en]

The invention relates to a portable processing system adapted for being worn by a user and comprising an input transducer for converting an input sound to an electric input signal, and a signal processing unit adapted for processing an SPU-input signal originating from the electric input signal. The invention further relates to use of such system. The object of the present invention is to provide an alerting device aiding a user in administering the dose of a hearing protecting agent. The problem is solved in that the signal processing unit comprises a monitoring part for monitoring and determining an accumulated sound dose AccD in the electric input signal from a start time t0 and for generating an alarm output at a threshold time t0+Δtth when a predefined dose threshold Dth is reached, wherein the predefined dose threshold Dth is set in relation to a recommended intake of a predefined hearing protecting agent to ensure an intended effect of the hearing protecting agent. An advantage of the present invention is that it helps a user to follow a prescribed dose administration scheme. The invention may e.g. be used in applications where a user taking hearing protecting medicine is exposed to acoustically different or noisy or loud environments.
