Abstract
音は環境情報源の重要な一つである。音の感覚器である耳は外耳,中耳,内耳から成る。耳からの神経信号は脳の聴覚中枢に達し,音の感覚と知覚を発生する。本編ではこの聴覚系の構造と機能を説明した。また,聴力と聴力損失について述べた。さらに網様体,視床下部-自律機能系,辺縁系を介する音の非特殊反応について解説した。音環境と人間の関係についてなお良く知るには,音の知覚と認識についての心理学的な考察が必要である。
Sound is one of the important sources of environmental information. The sensory organ for sound is the ear consisting of the outer-, middle- and inner-ear. Nerve-signals from the ear reach the auditory nervous center of the brain, and there produce the sensation and perception of sound. This article explains the structure and function of this hearing system. Hearing acuity and hearing loss are also explained. Moreover, non-specific response to sound through the reticular formation, hypothalamoautonomic system and limbic system is also described. For further information on the relationship between sound environment and man, psychological consideration of the perception and recognition of sound is needed.
