Core Technologies

To deliver even richer sound, Yamaha is continuing research into technologies in the fields of processing wood and metal materials, as well as keyboard and action mechanisms, sound sources, and acoustics.

Wood reforming technology Acoustic Resonance Enhancement (A.R.E.)

A.R.E. (Acoustic Resonance Enhancement) is an original wood reforming technology developed by Yamaha. Through precise control of temperature, humidity, and atmospheric pressure, the molecular properties of the wood can be manipulated into a more acoustically ideal condition, similar to the molecular characteristics of wooden materials in instruments that have been played for years.

Research to Analyze Vibrations and Acoustics of Musical Instruments

The shape of acoustic musical instruments, their structure, materials used, and other elements of their design have a major effect on the tones the instruments produce. For this reason, Yamaha evolves its instruments by using measuring and simulation technologies to study how the various parts of the main body of instruments vibrate and how the sound is generated by transmitting the vibration inside the instrument and into the surrounding atmosphere.

Muting system for brass instruments "Silent Brass™"

Yamaha’s "Silent Brass™" muting system for brass instruments allows users to practice or play at any time and in any place. This system consists of a Pickup Mute, which is smaller and lighter than in previous models, and a Personal Studio, which incorporates Brass Resonance Modeling technology that makes use of Yamaha’s unique signal processing technology. Application and fusion of these latest technologies enable players to hear more-realistic sounds and a more-pleasant feeling when performing and practicing..

In creating AV, PA, and networking equipment, Yamaha brings together its digital signal processing and network technologies, which are at the core of cutting-edge electronics technology, to deliver high-value-added products.

Aerodynamic sound control technology TWISTED FLARE PORT

One of the challenges in bass reflex speaker reproduction is to control air turbulence noise. Yamaha’s TWISTED FLARE PORT, is an aerodynamic sound control technology that can identify the noise generation mechanism and to reduce it by utilizing aerodynamic sound analysis and flow visualization measurement technology. As a result of the application of this technology, listeners can enjoy clear and rich low-frequency reproduction.

Virtual surround technology AIR SURROUND XTREME

Yamaha has worked for many years in pursuit of better virtual surround reproduction that gives the listeners a sense of "being there." The results of these research activities have been the development of the AIR SURROUND XTREME, technology through the application of a head related transfer function. Use of this function makes it possible to give listeners a clear sense of sound source location and a high quality of surround sound with a single speaker, and the sound is comparable to multichannel surround speakers.

Modeling technology Virtual Circuitry Modeling (VCM)

To recreate the depth of sound that can be obtained from analogue audio equipment, Yamaha has developed its VCM technology, which makes it possible to do precise modeling from the circuit element level to the overall circuit in the world’s best equipment. Yamaha’s Effect Program VCM Effect, which applies this technology, makes it possible to achieve the warmth of musical sound and is now incorporated in Yamaha digital mixers and electronic musical instruments.

TransAcoustic Piano

Yamaha’s TransAcoustic piano is a hybrid piano that combines an acoustic piano and a digital piano. Using a transducer (oscillating mechanism), the vibrations produced by the digital system are transmitted efficiently to the acoustic piano’s soundboard, and, without using a speaker system, the sound emerges from the soundboard. By incorporating the latest digital sound source technology, when the digital system is played, the strings of the TransAcoustic piano also resonate to produce a natural tone and resonance.
