Acoustic comfort is a state of an environment where the level of background noise and reverberation time (echo) are within comfortable limits for the human ear. In modern apartments with open layouts, panoramic windows, and minimalist design, the problem of “boominess” is particularly acute. Sound waves repeatedly reflect off hard surfaces—concrete, glass, and porcelain stoneware—creating an unpleasant hum and reducing speech intelligibility. However, few people consider that professional wall soundproofing is not the only solution. Properly selected and arranged furniture can act as an effective acoustic filter, absorbing up to 30-50% of unwanted noise and transforming a “concrete box” into a cozy space with soft sound.
