Price Differences by Performance (Dr-value)

Price image by performance

The performance of a soundproof room is expressed by the “Dr-value (decibels)”. The higher the value, the higher the soundproofing performance (= the less sound leaks).

Dr-valuePerformance ImageEstimated Price (1.5 Mats)
Dr-30Ordinary conversation can be heard. Piano sound is halved600,000 - 800,000 JPY
Dr-35Piano sound is “faintly” heard. For general streaming800,000 - 1,000,000 JPY
Dr-40Piano sound is almost unheard. For full-scale instrument practice1,000,000 - 1,500,000 JPY

Conclusion: For every increase of 5 in the Dr-value, the price goes up by approximately 200,000 yen.
