How many phone booths does an office of this size need?
There is no industry standard for the count. Published ratios run from one booth per 10 people to one per 25, where 1:10 comes from booth manufacturers and 1:25 from public agency design standards. Size against the headcount present on a peak day rather than total headcount, because over 40% of staff never use one regularly. And the only study with real data shows placement matters more than the number.

How many dB of sound reduction does a phonebooth need in an open office?
The number to ask for is speech level reduction Ds,A, measured to ISO 23351-1. Not NRC, and not Rw. Class A starts at 30 dB, class B runs from 25 to 30 dB. For everyday calls in an open office, class B is enough. For HR, legal or finance conversations, specify class A. A dB figure without a named standard and a test report number cannot be compared with any other brand figure.
