How many decibels is the sound insulation of a soundproof office booth?

Currently, various styles of soundproof booths are available on the market, all of which promote excellent sound insulation and the ability to create a good silent environment. The issue of sound insulation level in soundproof booths is a topic of great concern for consumers.

Most manufacturers advertise that their soundproof booths have a sound insulation level of around 35 decibels. However, the measurement of sound insulation level at 35 decibels is based on specific conditions.

A multifunctional soundproof booth has a sound insulation level of approximately 35 decibels (in an environment with 90 decibels of noise). Many people may misunderstand that if it can block 35 decibels of sound in a 90-decibel environment, then there should be no sound when it is in a 35-decibel environment. In fact, it doesn't work that way. The sound insulation level of 35 decibels has certain prerequisites and can only be achieved when the noise level reaches 90 decibels. The larger the noise, the more noticeable the sound insulation effect becomes. In scenarios with noise levels of 100, 120, or 150 decibels, the sound insulation level may be 40, 50, or 60 decibels respectively. In scenarios with noise levels of 70, 60, or 50 decibels, the sound insulation level may decrease to 25, 20, or 18 decibels respectively. A multifunctional soundproof booth does not provide complete sound isolation. Only a vacuum environment can achieve complete sound isolation.

Many consumers often have a lack of understanding about the principles of sound insulation in soundproof booths, and they may complain to the sellers after purchasing the product if they are not satisfied with the performance or if the sound insulation does not meet their expectations. However, in some cases, the sellers are not at fault. If the user's environment is already relatively quiet, there will still be some sound even when using the soundproof booth. This can lead to the users thinking that there is a problem with the sound insulation of the booth. When promoting the product, the sellers should clarify that the sound insulation level of 35 decibels is based on specific noise conditions and may not block 35 decibels of sound in every environment.
