Abstract
Abstract An audiometric survey booth to conduct basic hearing tests is padded interiorly with sound absorbing material at the top and sides to shut out exterior noises. At the top, portions of said material extend diagonally downward and thence diagonally upward while the material at opposite sides is non-parallel, flaring inwardly from the top in a downward direction, being so arranged that the ears of a person within my booth are particularly well shielded from outside noises.
