The phrase "acoustical test" is correct and usable in written English.
It can be used in contexts related to sound measurement, evaluation of acoustics, or testing sound-related properties in various environments.
Example: "The engineers conducted an acoustical test to determine the sound absorption properties of the new material."
Alternatives: "sound test" or "acoustic evaluation".

The sound absorptive performance of the acoustical unit is tested at different incident SPLs and in three typical configurations: 1) when the perforated panel (PP) directly contacts with the porous layer, 2) when the PP is separated from the porous layer by an air gap and 3) when an air cavity is set between the porous material and the hard backing wall.
For the acoustical parameters, the tests were additionally carried out using total call number as a co-variate (Table 3).
As part of this study large scale laboratory testing of acoustical and mechanical performance, durability and resilience to climate were performed.
