Description:

The MA 25 is a rugged, hand-held screening audiometer weighing just 2.16 lb (980 g) and sized to fit comfortably in one hand. Air-conduction testing spans 11 frequencies from 125 Hz to 8 000 Hz, with output levels from −10 dB HL up to 100 dB HL in 1 dB or 5 dB steps. Three signal modes—pure tone, pulsed warble and continuous warble—help reduce standing-wave artefacts. User-friendly rotary knobs select frequency, intensity and left/right channels, while choice of 3 × AA battery power or optional AC adapter keeps you testing anywhere. The MA 25’s straightforward design and soft carrying case make it ideal for school screenings, clinics or field use, and it’s built tough for daily point-of-care reliability.

Economic Advantage:

Before pocket audiometers like the MA 25, hearing screenings required bulky bench units or separate battery-powered headsets. By combining a full screening range (125–8 000 Hz, −10 to 100 dB HL) with true portability and battery/AC flexibility, the MA 25 slashes logistics and equipment costs. Clinics and outreach programs can deploy one lightweight device instead of dozens of specialized instruments, cutting training time and capital outlay while maintaining accuracy and durability. Its reliance on off-the-shelf AA cells and simple controls further reduces downtime and maintenance expenses.
