Acoustic technology of a bygone era

Ancient Inca musical instruments imitated animal sounds using only the flow of water. These are shamanic tools called “whistling huacos” or “whistling jars.” It is estimated that most of the original jars were made around 500 BC – 1200 AD in Peru. These beautiful works of art, which can be found in many museums, are generally unique in their exterior design but quite similar in the functional construction of the sound-producing mechanisms. Increase the volume!

An impressive acoustic technology: a chamber is filled with water, so when the glass is tilted, the water flowing from one chamber to another causes a pressure difference that forces air into the holes in the glass, similar to a flute that would work if a person blew on it.

From what we know, or what we have concluded from the analysis, these objects were used as shamanic tools used in ceremonies by the ancient cultures that made and used them. According to research, many of the jars found produce unique notes that can create binaural frequencies when played together.

This synchronization of pure tones can increase relaxation; change the production of hormones in the body; Reduce anxiety and stress by creating an auditory illusion of the two tones by creating a third tone.

In general, these instruments have had an interesting and dramatic flourishing in current culture; from sacred objects to decorative vessels and then back to sacred ceremonial tools over the last 1,000 years.
