Abstract
The use of smartphones by Brazilians in vehicles subject to vibration is increasing. Consequently, the analysis of the transmissibility of seat-to-hand vibration becomes necessary. Tests on a vibrating platform were developed in order to assess the influence of frequency, amplitude, gender and type of smartphone on this transmissibility. Six different stimuli (three frequencies and two amplitudes) were applied to volunteers who used two types of smartphones. The results showed that transmissibility increased with decreasing frequency and amplitude. In addition, the change in frequency or amplitude did not cause proportional behavior in transmissibility. In relation to gender, men accentuated the vibration compared to women, indicating less capacity to reduce vibration. As for smartphones, they had no influence on transmissibility.
