Sound is as important as lighting at the Court of the Seven Seas in Golden Gate Exposition.
faiqlA hlwte in Setting Sound
Public*s demand for better hearing achieved with amplifiers. Unlimited sound possibilities exist in industrial, educational and entertainment fields.
With the surface hardly scratched, Sound has an extremely optimistic outlook, according to leading sound merchandisers and manufacturers. New uses are heing found every day that are forever increasing the number of potential prospects. Because all this amplifier equipment uses radio components, this sound business will remain in the hands of the radio industry as long as they go after it.
As in the lighting and illumination field, where light intensities have consistently increased; there is likewise in sound, a growing need for increased sound levels or intensities. Persons should not have to strain to hear what is being said or going on. The fact that ordinary noise levels around us are getting greater will unquestionably help to boom sound.
INDUSTRIAL POSSIBILITIES UNLIMITED
Main use of sound will probably be in the entertainment and educational fields, and industrial applications. While the first two uses are quite well defined, the industrial possibilities are only now beginning to be discov
ered— and how these possibilities can be increased and developed depends entirely upon the resourcefulness of radio and sound men.
Practically every time a group of several dozen or more persons get together, there is a need for sound. Numerous tests have been made that show when an audience is noisy, it is usually because they cannot hear well — and consequently they shift about noisily or disregard the main program and talk to their neighbors. In some circumstances there have been reductions in the background noise of more than 10 decibels after the sound system is turned on. (And for those tbat don't know, 10 DB is a sound level ratio of 10.) Every meeting place, therefore, is a prospect for sound.
Entertainment places, one of today's largest sound users, will in the future continue to demand sound. Patrons must be able to hear well for proper enjoyment of what's going on. Because many of these installations have been made using cheap or improper equipment, there will be many modernizations and replacement of this equipment in years to come.
MAINTENANCE AND MODERNIZATION
Many of the components in even the better of the old systems, such as microphones and speakers, are quite crude when compared with today's new and improved types. Maintenance and modernization are, and will continue to be, good bets for the technically inclined sound men.
Exhibits of all types require sound if they are going to attract the full quota of observers. At the N. Y. World's Fair and the Golden Gate Exposition there are hundreds of sound systems helping to increase thf capacity of the various free and paid exhibits.
ANIMATED DISPLAYS THAT TALK
Animated displays should use sound to tell the story and attract attention. At the Chrysler Salon in New York, speakers are installed in the cars which tell about the features of the cars as the hood, doors, etc., open and close. In these displays, records are employed, but live talent has been used in other places with startling results.
