Eleven hearing-impaired subjects were tested using a speechreading test employing the CID Everyday Sentence Lists read by a male speaker under four different conditions: full beard and moustache, trimmed beard and moustache, moustache only, and clean shaven. The results indicated that varying amounts of facial hair do not have significant effects on speechreading performance. Mean scores for speechreading performance decreased somewhat with reduction of facial hair, however, as confirmed by a test of linear trend (p less than 0.05).
11名听力受损受试者接受了一项唇读测试，该测试采用由一名男性朗读的CID日常句子列表，测试在四种不同条件下进行：满脸胡须和小胡子、修剪过的胡须和小胡子、只有小胡子以及刮净胡须。结果表明，不同数量的面部毛发对唇读表现没有显著影响。然而，线性趋势检验证实，随着面部毛发减少，唇读表现的平均分数略有下降（p小于0.05）。
