Drawings from US Patent 1,962,565, 1934: the ring geometry and the apparatus

Since 1934

Two men. One year. Two ways to send a signal.

In 1934, two engineers on opposite sides of the world were working on the same question. One believed in a single, perfect frequency. The other built seventeen rings to send them all at once, and was granted US Patent 1,962,565 for it.

History moved on and left both behind. The patents stayed in the archives for ninety years.

Everything Amatro builds starts from that foundation. One exact note, or the full chord.

What to expect

Three phases most people describe

The first nights

Most people start with one tool and a simple evening routine. Ten to twenty minutes. It becomes a habit quickly.

The shift

With regular use, the routine settles in. Many describe a steadier, calmer rhythm to their evenings and mornings.

The baseline

Over time it stops being an experiment and becomes part of the house.

Individual experiences vary. Not medical devices. See full disclaimer below.
