Noise and the details of experiments: a reply to Poulton.
A recent paper has suggested that noise harms performance only through making it hard to hear key information from the task. This theory ignores essential facts in every experiment quoted. The harmful effects of noise are very similar to those of other arousing conditions which involve no acoustic stimulation. The theory thus illustrates the vital importance of careful attention to the detail of experiments.
