INTRODUCTION– ORIGINS AND THE USE OF SOUND IN ARCHITECTURE

Cymatics is the study of how sound vibrations create visible patterns on a medium such as sand, water, or a solid surface. Coined by Swiss scientist Hans Jenny in the 1960s, cymatics builds on earlier discoveries by Ernst Chladni in the 18th century, who demonstrated symmetrical patterns formed by vibrating metal plates. These patterns, known as Chladni figures, revealed the hidden geometries of sound and have inspired researchers, artists, and architects for centuries.

The project demonstrates how sound vibrations create visible patterns on a surface, a phenomenon known as cymatics.

A speaker emits frequencies starting at 600 Hz, decreasing by 50 Hz every 5 seconds until reaching 50 Hz.

The speaker is attached to a plastic surface sprinkled with salt or water to visualize the patterns formed by vibrations.

Lower frequencies produce larger, simpler patterns, while higher frequencies create intricate, detailed patterns.

An Arduino controls the frequency output and adjusts an LED’s brightness proportional to the current frequency.

A button allows the user to toggle the system ON or OFF, providing easy control over the experiment.

The project illustrates how materials respond to different frequencies, showcasing the concept of resonance.

Patterns form at nodal points, where vibrations are minimal, causing materials like salt to accumulate in specific areas.

The LED brightness serves as a visual indicator of the frequency, increasing with higher frequencies.

This experiment serves educational purposes, helping users understand sound wave behavior and its effects on matter.

Project render

The aim was to produce art installations ranging from Decorations to furniture, mostly coffee tables. Crucial aim was mostly in table form, where the sand is displayed under a glass block, below the sand is the sound system where you could wirelessly connect to to your gadgets and upload music. the music when emitted in form of waves, would displace the sand forming geometrical patterns ranging from flat 2D to 3D forms, adding height till the glass top.
