+Enables rapid iteration and exploration of design alternatives.

Limitations

The complexity of acoustic phenomena means that simulations are approximations. Real-world acoustic performance can be affected by unforeseen factors.

Reliability & validity

The study validates its model against real-world case studies, enhancing its reliability. However, the complexity of acoustic simulation introduces potential validity concerns regarding the perfect replication of real-world conditions.

Think critically
