Attention to auditory annunciation signals of elderly adults

在这项研究中，我们打算指出年龄对同时检测多个声音的能力的影响。此外，我们还研究了听觉告警信号的特征，这些信号是45岁到75岁的老年人可以很容易检测到的。总体而言，与年轻人相比，老年人的听力正在减弱。尽管如此，他们在日常生活中必须分别识别来自家庭电子产品的信号。我们合成了新的听觉信号样本，口哨水壶，重点关注波动强度。我们对老年失明成年人进行了心理实验，以揭示我们的新信号在日常生活中的有效性。参与者可以从我们的新信号中高精度地注意到沸腾的状态。当信号与日常噪音重叠时，该信号也很有用。声音不会与噪音混淆，直观地表达了沸腾的状态，并具有提取各种行为的可能性。

In this study, we were going to indicate the influence of aging in the ability of detecting multi-sound simultaneously. Further, we investigated features of auditory annunciation signals, which elderly adults, from 45 to 75 years old, can detect easily. Generally, elderly adults are diminishing hearings as compared to young adults. Even though, they have to recognize signals from home electronics separately in daily life. We composed samples of new auditory signal, whistling kettle, focusing on fluctuation intensity. We conducted psychological experiments with elderly blind adults to reveal effectiveness of our new signal in the situation of daily life. Participants could notice the state of boiling from our new signal with high accuracy. The signal was also useful when the signal were overlapped by daily noise. The sound was not confusable with noise, expressed the state of boiling intuitively, and had possibilities to extract various behaviors.
