- Abstract
- During the Conventions of the Society, symposiums on new motion picture apparatus and materials are held in which various manufacturers of equipment describe and demonstrate their new products and developments. Some of this equipment is described in the following pages; the remainder will be published in subsequent issues of the Journal.

Note that the decibel ratings mentioned in these papers are referred to the threshold of audibility. The new sound-level meters use 10–16 watts per sq. cm. as reference level. Accordingly, for any given sound a new standard sound-level meter will read approximately 7 db. higher than if the measurement were referred to the threshold of audibility. EXTERNAL
