    abstract     = "Sound Quality as a relatively new product parameter has become an important competition item among the car manufactures. Sound Quality metrics is the same as Sound Quality parameters, which can reflect most of the psychoacoustic properties of the human perception of sound. There are some standardized metrics, such as Stationary Loudness, Tone to Noise Ratio, Prominence ratio, but most metrics are not standardized. They all have the advantage that they conclude with a single number on the characteristic properties of the sound. 

Tonality is one of the Sound Quality metrics that is not yet standardized, but it is an important parameter affecting Sound Quality because it is proportional to the human perception of tonal contents in the sound. 

Terhardt s Tonality, which was proposed in 1892, is an algorithm for extraction of pitch and pitch salience from complex tonal signals. It is widely accepted that Terhardt s method is the foundation for Tonality metric definition. 

Studying Terhardt s algorithm is the start point of this thesis project. A {MATLAB} model according to Terhardt s algorithm is made. {AVC}++ implementation is also made in order to make it ready for Brüel \& Kj{\ae}r Sound Quality Application to use. Furthermore, both {MATLAB} and {VC}++ programs have been tested, and validated for further research work. 

An overall study of Stationary Loudness and Aures s Model of Tonality is also provided by our thesis. They broaden our knowledge in psychoacoustics research field."
