Catholic electroacoustical difficulties

Electroacoustical difficulties are catholic, i.e. universal, in that 99.44% of the installed public address systems degrade speech intelligibility. We explain the causes for degradation in transportation terminals, hotel ballrooms, and churches. Severe difficulties are cited in the Memphis Air Terminal, St. Patrick´s Cathedral in New York and all large hotel ballrooms. The use of 1/3 octave equalizers and time delay devices is debunked. For large convention meetings, the ASSP sound equipment is the only way to achieve satisfactory speech intelligibility. Churches can be improved by removing the microphones. The inability to obtain correct electroacoustical engineering is attributed to lack of education.
