Abstract
The utmost hearing distance in surrounded structures under natural phonation condition is 30 m as reported in the literature. Under the condition of taking optimization values, this paper brings forward a method which calculates the utmost hearing distance in a lecture hall under natural phonation condition and finds that the utmost hearing distance in surrounded structures is 20.32 m. Also, it is found that the utmost hearing distance between the speaker and the audience under free sound field is 7.96 m. This value agrees well with the recommended value of 8 m by the State. Such information will be useful for the architects when designing lecture halls.
