 note = {音響実験機器の諸特性は，使用期間が長くなると変化する．かつて，新しい機器はエージング （慣らし運転） を行い，使いこんだ機器も電源投入時にはエージング （暖機運転） を行うことが普通であった．ところが，今日では，電源投入とともに受聴実験や音響測定を始めることが少なくないように思う．ディジタル音響機器のエージングはもはや不要なのだろうか? 耳の諸特性も，使用期間が長くなると変化する．高齢者の耳は，そのフロントエンドの感度が低下するだけでなく，バックエンドのさまざまな機能が低下する．これは高齢者だけの問題なのだろうか? 本稿では，このような音響実験機器と耳のエージングについていくつかの事例を紹介する．, Various characteristics of acoustic experimental equipment change while using for a long time. My mentors taught me that we must perform pre-conditioning interim operation, or aging operation when we start using new equipment and that even equipment that are used for a long period need to be warmed up before starting the experiment. Nowadays, listening tests or acoustic measurements, however, are often started immediately after tuming on the equipment Is it no longer necessary to perform aging operation with the modem digital audio equipment? In the ears of the aging people, not only the sensitivity of the front end decreases but also various functions of the back end are deteriorated. Various characteristics of ears change while using for a long time. Is this a problem only for aging people? In this article, I introduce some examples of aging of acoustic experiment equipment and ears.},
