For these types of research, the input method plays an important role in the investigation of the auditory localization of sound sources in the collection of valid and meaningful data. The input method using LED array is based on the localization test, which is already used in the acoustics laboratory of the Peter-Osypka-Institute. The current input method via tablet with continuous input surface generates a high inaccuracy and error variance compared to the usual discontinuous input. To minimize this type of error for future measurements, an alternative method will be implemented as part of this bachelor thesis. The methodology of the alternative input method is based on the use of a controllable LED array with rotary encoder and push button. For this, an angular range from -90° to 90° with a 1° angular resolution shall be realized. The LED-array enables a visual representation while localizing sound sources.…
