Available in PDF, EPUB and Kindle. Book excerpt: CETTE THESE CONTRIBUE A L'ETUDE DU CONTROLE ACTIF DE L'ACOUSTIQUE D'UNE SALLE EN UTILISANT DES SYSTEMES ELECTROACOUSTIQUES. L'IDEE ESSENTIELLE EST DE CONSTITUER DES MURS ACTIFS PAR UN ASSEMBLAGE DE CELLULES ELEMENTAIRES AFIN DE CHANGER LA REPARTITION ENERGETIQUE D'UNE SALLE. CHAQUE CELLULE DOIT PERMETTRE DE REGLER LE NIVEAU DE RETOUR DU HAUT-PARLEUR A UNE VALEUR DESIREE TOUT EN CONTROLANT LA STABILITE DU SYSTEME. UN ENSEMBLE DES CELLULES CONVENABLEMENT COUPLEES POURRA ALORS CONTROLER LE COEFFICIENT DE REFLEXION GLOBALE D'UN MUR ACTIF. PAR CONSEQUENT, LE TEMPS DE REVERBERATION ET LES PREMIERES REFLEXIONS D'UNE SALLE SERONT CONTROLES. UNE STRUCTURE D'UNE CELLULE ELEMENTAIRE DU SYSTEME DE MUR ACTIF EST PROPOSEE. DEUX FILTRES ADAPTATIFS SONT INTRODUITS POUR CONTROLER RESPECTIVEMENT LA STABILITE ET LE NIVEAU DE RETOUR D'UNE CELLULE DU SYSTEME. LES ALGORITHMES DE CALCUL DES DEUX FILTRES ADAPTATIFS SONT PRESENTES. LES PRINCIPAUX RESULTATS THEORIQUES SONT ILLUSTRES SUR DES SIMULATIONS. LE PROBLEME DE L'ORGANISATION DES CELLULES D'UN SYSTEME DE MUR ACTIF EN VUE DE RECONSTITUER UN CHAMP SONORE LE PLUS NATUREL POSSIBLE A ETE ABORDE. LES RESULTATS DE SIMULATION DE DEUX TYPES DE MURS (UN MUR ACTIF ET UN VRAI MUR DE MEME DIMENSION) ONT ETE COMPARES. LA FAISABILITE PRATIQUE EST DISCUTEE. UNE REALISATION TEMPS REEL D'UNE CELLULE A ETE IMPLANTEE SUR UNE CARTE SPECIALISEE (TMS 320C30). LES PERFORMANCES DU PROTOTYPE D'UNE CELLULE SONT TESTEES NOTAMMENT EN CE QUI CONCERNE LA STABILITE D'UN COUPLE MICROPHONE HAUT-PARLEUR. UN CALCUL ACOUSTIQUE THEORIQUE SOUS DES HYPOTHESES SIMPLIFICATRICES EST DONNE. NOUS POUVONS DONC EVALUER EN FONCTION DU NOMBRE DE CELLULES LE TEMPS DE REVERBERATION D'UNE SALLE A PARTIR DE CARACTERISTIQUES MESUREES DANS CETTE SALLE. ENFIN UN PREMIER PROTOTYPE SIMPLIFIE D'UN MUR ACTIF EST PRESENTE

Download or read book The Memetics of Music written by Steven B. Jan and published by Ashgate Publishing, Ltd.. This book was released on 2007 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Richard Dawkins's formulation of the meme concept in his 1976 classic The Selfish Gene has inspired three decades of work in what many see as the burgeoning science of memetics. This study is the first musicologically-orientated attempt systematically to apply the theory of memetics to music. In contrast to the two points of view normally adopted in music theory and analysis - namely those of the listener and the composer - the purpose of this book is to argue for a distinct and illuminating third perspective. The perspective is that of the (selfish) replicated musical pattern itself, and adopting it is central to memetics.
