ABSTRACT
Indoor noise is very common in many places, because sound waves are kept inside the confined spaces of a room, where a higher sound level is present and will absolutely have the presence of noise. for the average person, noise is considered as the level of sound that is intolerable to the ears. On the other other hand, sound is considered as noise if the sound level or loudness reaches 80 decibels or higher, in reference to the standard of science.
This study described the sound level of two different dimensions of rooms in the Rockbox establishment located in Smallville, Iloilo City. Rockbox is a new establishment in the Smallville complex is the chosen candidate for the purpose of this study because of the popular game Rock Band which is available in their Play Station 2 game console. This game is very similar to karaoke machines, only that there can be a maximum of four participants can play the game, where each can hold a game controller in the likes of the essential musical instruments in a music band (drums, guitar, bass, and microphone). The game consoles are placed inside private rooms that can be rented by customers with a consumable time limit.
In this study, the main aim is to compare the sound level produced by customers in two different dimensions of the private rooms in Rockbox, one big and one small. The situation of the sampling of data is the normal activities of the customers who rented the room. The number of individuals inside, as well as the volume and random sounds they make are independent variables of the study.
An Explorer GLX Data logger with an available digital decibel meter was used to record data for each of the two rooms. Three samples of data were recorded for each room where one sample is equal to one hour of recording. After sampling the data, raw data was processed in a laptop with Data Studios software. A table of raw data along with a graph for each sample was produced for comparing the average sound level produced in the two rooms. In the results, the average sound level for the small room is 95 decibels while in the big room, there is an average of 89 decibels. Through careful study of results, there were many reasons why the sound level of the smaller room was higher, but the main reason is that the dimension of the room kept more sound in, whereas the other room has a wider dimension, giving a longer time for sound to disperese.
