Mechanical response measurements of real and artificial brass players lips
Résumé
Mechanical frequency responses of human and artificial lips in brass instrument playing have been measured using a high-speed digital video technique, in an attempt to classify the true nature of the ‘lip-reed'. Four semi-professional human players were used, and three notes played on a trombone were studied. All measurements revealed a strong mechanical resonance with ‘outward striking' behaviour; the played note always sounded above this frequency. Several measurements also showed a weaker second resonance, above the played frequency, with ‘inward striking' behaviour. The Q-values of the dominant resonances in human lips were lower than those typical of artificial lips.
