The first study investigated a group control procedure for suppression of excessive sound‐intensity levels in a regular public school classroom. Reinforcement consisted of a 2‐min addition to the class gym period and a 2‐min break after maintenance of an unbroken 10‐min quiet period as monitored on a decibel meter. Transgressions of the sound limit (42 decibels) resulted in a delay of reinforcement by the resetting of the timer to the full 10‐min interval. The results indicated that these procedures were highly effective in suppression and control of sound intensities. The second experiment utilized a similar procedure coupled with a procedure of eliminating out‐of‐seat behavior. Experiment III studied the effects of Exp. II procedures on a single student's out‐of‐seat behavior rate. All procedures were found effective.
