Noise measurements were made in cinemas during the showing of four films, to establish whether the noise levels from films might pose a risk of damage to hearing. The L Aeq levels for the full playing time of each film were all below 80 dB(A). Noise levels did sometimes exceed 90 dB(A) but this was never for more than a total of two minutes, and was usually for only a few seconds. Repeat L Aeq levels for the same films were shown to vary by 3-4 dB across different cinemas. Based on this limited sample of films and cinemas, there is no evidence that sound levels in cinemas cause permanent damage to hearing.
