Nasal formant
The nasal formant is a formant as a resonance-like accentuation of partial tones in the frequency range between 1500 and 2000 Hertz, which produces this effect of the nasal effect.
In the case of speech sounds, an increase in level in this frequency band is due to the natural frequencies of the suprapalatal space. If the nasal effect is not in the natural structure of the language, as is the case with some nasalized vowels in French, or is caused by anatomical or pathological conditions, according to research by Günther Habermann it is an expression of the sensual in the voice and when laughing .
With musical instruments , efforts are made to avoid an increase in level in this Näsel frequency band, as this leads to an undesirable “nasalization” of the timbre . According to the work of Fritz Winckel , it is even z. For violins , for example , the extent to which the partial frequencies in the range between 1500 Hz and 2000 Hz are attenuated in the violin spectrum is a quality feature. The only exception is the saxophone spectrum, which usually has a pronounced nasal formant at frequencies below 1800 Hz, which explains the slightly nasal sound effect of the saxophones .
