The MA 39 Audiometer, available from SI Instruments , is a precision instrument designed to permit simple, rapid and reliable hearing tests. Applications range from school testing programmes to pre-employment examinations and monitoring audiometry for hearing conservation programmes. The audiometer instrument provides pure tone frequencies and a full dynamic range.
The following are the features of the MA 39 Audiometer:
- Full range electronic attenuator (-10 dBHL to 110 dBHL mid frequencies), with all input/output switching and routing performed electronically.
- Large LED numeric displays show the selected frequency and HL intensity.
- Small individual LED’s are used to show the selected function.
The new model MA 39 Audiometer retains the side mounted controls for frequency and HL setting as well as the dual present/interrupt buttons that is familiar to Maico audiometer users.
All functions, actuators/push button controls, provide a tactile feedback to the operator whenever a function is selected or operated. A bright LED indicator is also associated with the selected function.
