Abstract
The objective of this research was to construct the resonance of sound waves in an air experimental media by comparing the velocity of sound waverecord at the maximum value using listening method and data logger program. The result presented that the speed of sound wave from listening was at the frequency of 500, 550, 600, 650 and 700 Hz were 349, 341, 351, 354 and 350 m/s respectively. The measurement errors were 0.14, 2.43, 0.42, 1.28 and 0.14 % respectively. The average sound velocity in the air by listening method was 349 m/s and the error percentage was at 0.12 %. The velocity of sound record by the data logger at frequency was 500, 550, 600, 650 and 700 Hz respectively, while the sound speeds were 344, 354, 346, 348 and 355 m/s respectively. The percentage error was at 1.57, 1.28, 0.42, 1.00 and 1.57 %. The data logger speed was 349.4 m/s, and the error percentage was at 0.05 %. The average speed of sound waves in the air was determined by the listening and the speed of sound using a data logger compared to the theoretical speed lof soundwith a deviation of less than 1 %, which can be used as an experimental laboratory media.
