A large bare floor is undoubtedly bad for acoustics, for when a room is filled by an audience the hearing is much improved.
The three hundred-foot monoliths offer superb acoustics for any type of performance.
His investigations occupied almost the whole field of science, including physiology, physiological optics, physiological acoustics, chemistry, mathematics, electricity and magnetism, meteorology and theoretical mechanics.
The theory of proportion, and the study of acoustics and music were considerably advanced by his investigations.

Most of Wollaston's original work' deals more or less directly with chemical subjects, but diverges on all sides into optics, acoustics, mineralogy, astronomy, physiology, botany and even art.
In the course of these varied and prolonged researches from 1865 to 1877, he also made important contributions to the science of acoustics; and he established by several series of laborious observations, extending over many years and along a wide coast range, the correctness of G.
Barnes, Practical Acoustics (1898), treats the subject experimentally.
For some years he continued making experiments in acoustics, following out his own ideas and devising many beautiful and ingenious arrangements.
ACOUSTICS (from the Gr.
The term "acoustics" might, however, with advantage be reserved for the aspect of the subject more immediately connected with hearing.
In acoustics he invented, about 1819, the improved siren which is known by his name, using it for ascertaining the number of vibrations corresponding to a sound of any particular pitch, and he also made experiments on the mechanism of voice-production.
In acoustics his principal work was a research on the transmission of sound through solids, the explanation of Chladni's figures of vibrating solids, various investigations of the principles of acoustics and the mechanism of hearing, and the invention of new musical instruments, e.g.
The efforts which were consequently made in the early days of spectroscopy to discover some numerical relationship between the different wave lengths of the lines belonging to the same spectrum rather disregard the fact that even in acoustics the relationship of integer numbers holds only in special and very simple cases.
They were written at the request of the princess of Anhalt-Dessau, and contain an admirably clear exposition of the principal facts of mechanics, optics, acoustics and physical astronomy.
