Sound and vibration of Terengganu traditional boat

Abstract

Traditional boats were still the main transport to cross from Seberang Takir and Pulau Duyong to Kuala Terengganu. However, nowadays due to less response from people, traditional boats currently being elevated as a boat tours but still maintaining the traditional design which was based on wood. However, since the boat was constructed from wood and has been already used for a long time, noise and vibration becomes the factor that cause discomfort to passengers. Noise and vibration also factors that can disrupt passengers' concentration and more worse, it can cause harmful effects on passenger's health. Noise also comes from a strong vibration on traditional boats. The passengers of traditional boat were more susceptible to the distraction due to an increase in noise. This thesis was focused on determining the noise and vibration in the traditional boats in Kuala Terengganu and mainly to find solution to reduce the noise and vibration. Data for noise and vibration were taken by using a Sound Level Meter and Vibration Meter. Next, data were analyzed based on the basis of experiments which were usage of dampers and application of enclosure on the main engine. From the results of field work, found that the sound pressure level of 95 dB was considered as unsafe levels to human. Results also show that the usage of damper can reduce vibration and the application of enclosure can reduces noise in the main engine.
