Pure tone testing checks your ability to hear tones of different pitches in each ear. The MA 28 is designed with state of the art audiometric circuitry, which ensures fast, accurate test results. Bone Conduction audiometry is conducted by placing a bone oscillator behind the ear instead of using headphones. This is a helpful test in determining if hearing difficulty is conductive or sensorineural in nature.
The RadioEar B71 bone conductor comes standard with the MA 28, an international gold standard accessory. MAICO engineers our products with quality components, ensuring lasting performance and product reliability. Operate in English or Spanish.
