    For measuring the impulse response and the acoustic parameters of a room, it is common to use an omnidirectional dodecahedron loudspeaker as a sound source. The use of a dodecahedron loudspeaker is the most reliable and common way of conducting acoustic measurements, although there are alternative ways of sound field excitation. The dodecahedron loudspeaker is utilized by many impulse response measurement methods, such as Maximum Length Sequence (MLS), Inverse Repeated Sequence (IRS), Time-stretched Pulses, Sine-sweeps, etc. Unfortunately, the required dodecahedron loudspeaker equipment is costly. This thesis statement titled “Measuring Acoustic Parameters Using a Conventional Directional Loudspeaker” discusses a new method of measuring the acoustic parameters of a room, not by using an omnidirectional loudspeaker as usual, but by using a loudspeaker for domestic use. The aim of this dissertation is to create a new method that will provide accurate results compared to measurements using a dodecahedron loudspeaker, but with minimal cost. During this thesis statement, impulse response measurements were taken by applying the method to spaces of different size and different source-speaker locations. Meanwhile, measurements were taken using a dodecahedron loudspeaker. The acoustic parameters that resulted from the experimental data were extracted and compared. From the results that emerged, conclusions are drawn on the effectiveness of the method, and future work is discussed.
