An experimental resonance tube setup consisting of an economy resonance tube, laptop computer, desktop speaker and digital thermometer was developed and utilized inside the physics classroom in the Bukidnon State University, Malaybalay City, Bukidnon. The experimental values of speed of sound vsound at room temperature were deduced through frequency-vs-harmonic number (f-vs-n) experiments. These experiments include open-pipe and stopped-pipe procedures in several trials. Room temperature has been found changing at different time intervals of the day and weather conditions so that frequency-vs-harmonic number (f-vs-n) were performed at different room temperatures at different time intervals.
