Equal Intensity Contours for Whole-Body Vibrations Compared with Vibrations Cross-Modally Matched to Isophones

Abstract. In this study, two experiments were conducted to determine the curves of equal intensity perception for sinusoidal vertical whole-body vibrations (WBV) of seated subjects over the frequency range from 10Hz to 250Hz. Vibrations were presented to subjects using a at hard seat. In total, 10 participants were asked to match the intensity of dierent vibrations, using a method of adjustment. The obtained contours were compared with the threshold of vibration and to vibrations cross-modally matched to tones from isophones. The shapes of the equal intensity contours in the present study show reasonable agreement with the contours from other studies despite the use of dierent methodologies and experimental questions. The contours show a characteristic similar to the perception threshold. No dependency of vibration magnitude on the shape of the contours was found in the applied dynamic range. However, large inter-individual variations were observed. The results imply that vibration curves that are cross-modally matched to isophones show similar characteristics

Development of a social survey questionnaire of reactions to vibration in residential buildings

A social survey questionnaire has been developed to determine human responses to vibration in residential environments. The overall aim was to produce a robust methodology for obtaining responses that could be combined with vibration measurements so as to investigate dose-response relationships for vibration in residential buildings. The vibration considered included that from sources outside the control of residents (e.g., road, rail, industrial, construction). This paper describes the development of the questionnaire and explains its structure and content. A review of social surveys and field and laboratory studies of vibration and noise is included. Methods of analysing responses obtained to the questionnaire are summarised

A social survey questionnaire of human responses to vibration in residential buildings

The development, structure, and content of a social survey questionnaire designed todetermine human responses to vibration in residential environments are presented. Theoverall aim of the questionnaire was to obtain responses that could be combined withvibration measurements so as to investigate dose-response relationships for vibration inresidential buildings. The questionnaire seeks to obtain information on how the vibration isperceived in residential environments and encompasses common sources of vibrationoutside the control of residents (e.g., from road, rail, industrial, construction operations).Methods of analysing responses obtained with the questionnaire are summarised
