Abstract
This study was conducted based on interdisciplinary approach, physics, and vocal music science, it could be used as an alternative activity to support student learning about a sound wave. The aim of this study was to analyze the voices of the school choir singers using Android App namely Spectroid… The result showed that 16 of 18 singers had been in the right position based on their type of voice. There are two singers had not been in the right position because they positioned in a bass group which their voice could not reach the minimum limit of Bass frequency. The Soprano group which had the frequency range 148.6 Hz-1045.6 Hz, 6 of 8 singers could be in mezzosoprano and 4 of them could be in Alto. The Tenor group (96.4 Hz-697.0 Hz), 1 of 2 singers could be in Baritone but both of them could not be in Bass. The Bass group (81.4 Hz – 493.8 Hz), 2 of 4 singers are true Bass but all of them could be in Baritone and 1 of them could be in tenor. All of 4 singers in Alto group (171.2 Hz-702.0 Hz), only positioned in Alto.
Highlights
School choir is one of extra-curricular activities that has been favoured by students, they sing in a group, each of them has own sounds characteristic
The sounds are produced by the physical system, the vocal human track, which modulates the pitch of the voice[1], so that every people, include the choir singers, have different characteristic of the sounds
There are several studies related both to acoustic analysis of human voice and musical instruments, such as the Acoustical characteristics study that conducted on the voice of school teachers in Iran [2], there are studies to compare the experimental results of Bonang Barung waves superposition simultaneously and mixing using Audacity and MATLAB[3] and to measure the sound intensity produced angklung using a sound level meter[4]

There are several studies related both to acoustic analysis of human voice and musical instruments, such as the Acoustical characteristics study that conducted on the voice of school teachers in Iran [2], there are studies to compare the experimental results of Bonang Barung waves superposition simultaneously and mixing using Audacity and MATLAB[3] and to measure the sound intensity produced angklung using a sound level meter[4]. The study of acoustic has both physic and vocal science side. Acoustic is a part of physics science that related to sound study. The sinusoidal waves are characterized by their amplitude, frequency and phase as shown by the harmonic sound wave function (1) [9]
