❓ FAQ

How does sound affect medical treatments?

Sound waves can be used to precisely target and destroy tumors without invasive surgery, potentially offering new treatments for various ailments, including Alzheimer's disease.

What is cymatics?

Cymatics is the study of visible sound and vibration, where sound waves are transformed into visual images by demonstrating the wave patterns that sound frequencies produce in different mediums such as water or sand.

Why is acoustic engineering important in public spaces?

Acoustic engineering ensures that spaces like train stations, theaters, and concert halls have clear acoustics, improving safety by ensuring announcements can be heard clearly and enhancing the overall auditory experience.
