Professional books on architectural acoustics are aimed chiefly at readers with mathematical or technical background, usually graduates of electronics or physics faculties. Such studies have only a limited usefulness to architects, who intend not to study architectural acoustics as a separate area of knowledge, but to search for an inspiration regarding acoustically correct architectural solutions.The materials included in the multibook are to help architects in correct and unassisted solving of common and unsophisticated noise protection and interior acoustics problems. This type of knowledge is most useful in conceptual design works related to architectural acoustics, as well as in mutual understanding of different priorities that architects and acoustician working together may have.
