As part of the described tests, measurements of the acoustic insulation of a wall fragment were carried out in situ, in a room whose reverberation time in the area of the tested sample was modified by the use of a material absorbing the acoustic wave and was 1,09 or 1,71 s. The measurements carried out showed a significant impact of changes in roomreverberation parameters on the standard indicators of the field assessment and, consequently, on the possibility of carrying out the assessment. The results presented indicate the practical limitations of the method resulting from environmental conditions in terms of room reverberation. The article proposes a relatively simple method that allows for a significant improvement in the parameters of the acoustic field to a degree sufficient to carry out measurements.
