Electric Pianos Rss

A Look at Piano Acoustics

Standard acoustic pianos are known to produce a unique set of sounds which are directly linked to their physical construction – digital pianos are engineered to re-produce the delicacy and intimacy of this sound. Piano purists focus on the inability to truly replica the details and richness of the acoustic sound in electronic form, but advanced electric acoustic technologies are increasingly coming closer to this level.

The sound emanating from an acoustic piano is inherently linked to its strings, which must be regularly tuned to ensure they remain true to form. Strings vary in thickness, ranging from 1/30 inch, which produces a high-end vibration to a third of an inch, a thickness that produces a higher level of base. In general, the thickness is proportional to an octave on the piano – so that pianos are designed to reproduce the vibrations of strings accordingly.

The vibrations also produce overtones, which oscillate to produce harmonics which are pleasant to the ear. These oscillations are difficult to reproduce, although advanced digital pianos can now capture these frequencies with a high level of accuracy. The quality of the strings is directly related to the ability to produce high-quality sounds. As a result, tuning a grand piano requires important attention paid to the detail.

A variety of measures of the scale vibration, including the Railsback curve, capture the deviation between a tuned piano and a perfect scale. The unique sounds produced from a piano, including overtone vibrations, give it a unique sense of sound quality.
