We will evaluate what sound pressure, speaking rate, and sampling frequency make the voice guidance of home appliances easy to hear.
**Characteristics of Evaluators** As basic auditory data, measurements will be taken on the following items: - Audiometer (250, 1000, 4000 Hz) - Sweep tone **Potential Insights from Analysis** ■ Regarding Sound Pressure - Differences between the elderly and younger individuals, and whether these differences change with distance - Guidelines for sound pressure (optimal values, higher sound pressure, lower sound pressure) - Relationship between sound pressure, speech rate, and sound quality ■ Regarding Speech Rate - Guidelines (speech rate that 95% of people can understand) - Sound pressure that is "easy to understand" even with a fast speech rate - Sampling frequency that is "easy to understand" even with a fast speech rate ■ Regarding Sound Quality - Guidelines (sampling frequency that 95% of people can understand) ■ Regarding "Overall Ease of Listening" - How sound pressure, speech rate, and sampling frequency are related to "overall ease of listening" - Using data on "overall ease of listening" to group evaluators. This will clarify the characteristics of each group, allowing us to understand what kind of individuals should be targeted when deciding on things like voice guidance.
