An audiometer comprising: a database storing a non-transitory digital test signal associated with a desired test sound; a digital to analog converter (DAC) that converts the digital test signal to an analog signal; headphones that produce a sound responsive to the analog signal; a microphone that registers the sound; and a controller that adjusts the digital test signal so that the sound produced by the headphones has acceptable fidelity relative to the desired test sound to have the sound be useable in a hearing test. |
