The objective of the thesis is to determine the target acoustic parameters of the studio and to propose a technically justified optimal acoustic treatment solution that achieves these target values. In practice, audio engineers frequently encounter inadequately acoustically treated spaces, particularly in the low-frequency range, which results in an uneven frequency response, a distorted sound image, and unreliable sound perception. The main problem in the room was the presence of pronounced modal frequencies and standing waves in the low-frequency range, which resulted in an uneven frequency response, excessive reverberation time, and an undefined sound unsuitable for music production. Software-based calibration tools can only partially mitigate these deficiencies; therefore, proper acoustic design of a space remains essential for high-quality music production. An understanding of room acoustics is important both in small recording environments and in larger concert and cultural venues. The aim of this bachelor’s thesis is to perform acoustic measurements of a selected space, design and implement appropriate acoustic treatment elements, and evaluate the achieved improvements through subsequent measurements. The work will be based on a review of relevant literature, the execution of measurements, analysis of results, and a comparison of conditions before and after acoustic treatment. The results of this thesis confirm that appropriately designed acoustic treatment can significantly improve the acoustic performance of a small studio space. Measurements before and after treatment showed reduced reverberation time, between 200 Hz and 7 kHz, the RT20 decreased from an initial range of 0.75–1.3 s to 0.1–0.2 s, improved frequency response, and reduced influence of early reflections and room modes, particularly in the mid- and high-frequency ranges. The use of broadband absorbers improved sound clarity, intelligibility, and stereo image accuracy. Despite these improvements, low frequencies remain the greatest challenge due to the modal behaviour of small rooms. Meeting professional standards and recommendations, such as those specified by the EBU Tech 3276, often requires more complex and costly acoustic solutions.
This thesis demonstrates the importance of a systematic and interdisciplinary approach combining room acoustics, acoustic measurements, and the design of acoustic treatment elements.
