* Acoustic Resonance Enhancement (A.R.E.) is Yamaha’s proprietary technology for artificially stimulating the same changes in wood that occur during natural aging in a short time to improve acoustic characteristics. Through precise control of temperature, humidity, and atmospheric pressure using a specialized device, the acoustic properties of the new wood can be manipulated to realize a more ideal condition that is similar to the acoustic characteristics of wood materials in instruments that have been played for years. Prior timber enhancement technologies often utilize chemical agent-based enhancement methods; A.R.E., however, does not use any chemical agents in the processing stage. Therefore, this technology has a lower environmental impact.
