| Now standardized: HEAD acoustics develops new psychoacoustic analysis Tonality (Hearing Model) |
| The NVH Research department of HEAD acoustics has developed a new algorithm: the psychoacoustic analysis Tonality (Hearing Model). The new analysis, based on an improved hearing model by Prof. Dr. Roland Sottek is now part of the standard ECMA-74 15th edition (June 2018). Within the context of the standardization, the algorithm has been tested and evaluated by an international committee of experts. |
| From howling caused by an electric vehicle to a whistling sound of IT equipment, almost every acoustic engineer has to deal with disturbing tonal noise issues. If a product or a machine causes tonal noise components, it will have a negative impact on its perceived overall quality. The analysis Tonality (Hearing Model) determines whether or not a sound contains prominent tonalities. If tonalities are present, the analysis will even determine their strengths. The outcome shows a better correlation to the by humans perceived tonality than other existing approaches. |
