Strengths & Limitations

Strengths

  • +Utilized simulation software for quantitative analysis.
  • +Included both objective measurements and subjective user perceptions.

Limitations

It can be difficult to accurately measure acoustic properties without specialized equipment and software.

Reliability & validity

The use of established acoustic metrics (RT30, C50, D50) and simulation software lends quantitative reliability. Validity is supported by the inclusion of student perceptions, though subjective elements can introduce variability.

Think critically

To what extent can material choices compensate for poor architectural design in achieving good classroom acoustics?
