Abstract

This paper describes the development and testing of an Arduino-based audiometer for measuring ten levels of sound generated by a speaker. The device uses an Arduino UNO platform and includes an OLED display, a MAX7219 matrix LED, and a push-button for the person being tested to indicate when they hear a sound level. The results showed that the device could accurately measure sound levels and provide a reliable measure of hearing sensitivity. Arduino-based audiometers have several advantages over traditional audiometers, including low cost, portability, and customizability. However, the accuracy of these devices compared to traditional audiometers is still an area of concern, and further research is needed to validate their use in clinical settings. This paper contributes to the growing body of literature on the development and validation of Arduino-based audiometers and demonstrates the potential of these devices to provide an affordable and accessible way to diagnose hearing loss.
