Description
This study examines a rarely considered acoustic consequence of the piano hammer–string collision: the direct sound produced by the hammer’s rapid acceleration at impact. Using analytical methods and 2D finite element modelling, the resulting acoustic pressure is simulated and combined with the synthesised responses of a stiff string and soundboard radiation. The composite signal is analysed to assess the relative relevance of the impact-generated sound across the piano range. Results show that its contribution is generally minor, particularly for lower notes, and while typically masked under normal playing conditions, it may become noticeable in recordings with microphones placed near the action.
