Changes in the number of transient and all‐night sleep spindles by traffic noise of 55 to 65 dB(A) were studied. The sleep parameters were the number of spindles per minute in stages 2, 3, and 4 (S2, S3, S4) and the total number of spindles divided by the total sleep time. A transient decrease in the number of spindles was recognized and after noise exposure, the number of spindles increased to near the pre‐exposure level. Spindles were counted from S2, S3 and S4 for all‐night sleep. The number of spindles in all‐night sleep by noise exposure increased. The authors explain discrepancies in the results by a compensatory brain mechanism of sleep disturbance due to passing truck noise.
