This book is intended for those who are active with sound amplification and sound distribution. The book provides information on adapting sound systems and/or transducer to the given acoustics like in open, half-open and closed spaces. An important aspect is how loudspeakers can be adapted to cover all types of surroundings. Very often a choice has to be made from a wide range of loudspeakers. On the other hand a combination of loudspeakers must be developed and composed in order to adapt the loudspeakers to the given acoustical circumstances. The question of which loudspeaker is the correct choice and how they need to be set-up so that speech and music are fully comprehensible in all kinds of acoustical and noisy circumstances. This book gives a full answer to these questions. The reader is also made aware of the design of loudspeakers on the basis of Small and Thiele parameters. With thorough calculations and the visibility of the out coming of these calculations by simple software it is possible to convert the acoustic and mechanical elements of the loudspeaker into electrical analogues so that the loudspeaker is simulated on the PC. Using an example the calculations mentioned above can be supported. Finally the full reference list simplifies the task of the reader in finding the information they require. a€œIa€™ve been fascinated by the possibilities of Electro-acoustics since I was 10 years old and now I am very pleased to be able to share the knowledge that I built up over 40 years working in the Electro-acoustics division of Philips.a€ My work experience was supplemented by giving lectures on electro-acoustics at the post-academic courses on acoustics in Antwerp (Belgium)Example: 8.3. with L1 = 94 + Ssl +Lv dB: Ldif =Ssl+Lv- 10logQ- 10logV+10logT+ 118, 5 dB The data are: Lv = 10 dB, Ssl= -5 dB, Q = 10, V = 10000 m3 en T = 5 ... The electrical and acoustical levels can be shown in such a level diagram fig 8.1.
