Attention to auditory annunciation signals of elderly adults

在这项研究中，我们将指出衰老对同时检测多个声音的能力的影响。此外，我们研究了听觉信号的特点，老年人，从45岁到75岁，可以很容易地检测到。一般来说，与年轻人相比，老年人的听力正在下降。尽管如此，他们在日常生活中必须分别识别来自家用电子设备的信号。我们组成了新的听觉信号，哨声水壶，重点波动强度的样本。我们对老年盲人进行了心理实验，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。当信号与日常噪声重叠时，该信号也是有用的。该声音不会与噪声混淆，直观地表达了沸腾状态，并有可能提取各种行为。

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.
