NC-v4 EQc9:Acoustic performance

Hello Leed User community,

I am looking at the acoustic performance tool for LEED v4.

At the table for Sound transmission STC rating I don' t understand the adjacency combinations there where "Other" is mentioned. For example Retail is combined with "Other" and under STC rating is written "specify".

What is meant under specify; What is the minimum allowed STC rating at this case? Does there a limit exist or not?

Thanks
