Objectives

Narrative objectives1

To develop a wearable sensor-fusion device that extracts the frequency, duration, and intensity (sound pressure) of vocalization from vibration data, to verify its reliability, and to examine the relationships between daily vocalization and physical activity, physical function, and respiratory function in community-dwelling older adults.

Basic objectives2

Others

Basic objectives -Others

Study 1: In 10 healthy adults, the accuracy of distinguishing self-generated from others' vocalization and of separating chewing sounds from vocalization will be verified against video recordings. Study 2: In 6-10 community-dwelling older adults wearing the device during the daytime for 7 days, daily vocalization time, its association with physical activity, and sex differences will be examined. Conversation content will not be recorded or analyzed.

Assessment

Primary outcomes

Daily vocalization time measured by the device, and the reliability coefficient for distinguishing self-generated from others' vocalization against video recordings

Key secondary outcomes

Vocalization frequency, vocalization intensity (sound pressure), step count and physical activity, vocal capacity (maximum sound pressure, maximum phonation time), vital capacity, respiratory muscle strength (MIP, MEP), grip strength, skeletal muscle mass index (SMI), Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC), device usability, and adverse events

Other

Other related information

This study consists of two parts. Study 1 develops a wearable sensor-fusion device (M5Stack-based) and verifies its reliability; Study 2 examines its feasibility in community-dwelling older adults. The device processes only vibration amplitude data, and conversation content is neither recorded nor analyzed. In Study 1, conversations are video-recorded solely for accuracy verification, and the recordings are deleted promptly after verification. All measurement devices are removed in private spaces such as bathrooms and toilets. This approval (No. 26-036) also covers data analysis and publication for a preceding study (approval No. 24-029, UMIN000063074).
