A device 50 for simulating a blown musical instrument 12 such as a trumpet, saxophone, flute or horn includes: a mounting portion for connection to the instrument; a transmitting means configured to transmit a non-audible wave, such as an ultrasonic wave, inside the body of a blown instrument; and a receiving means configured to detect the waveform within the body of the instrument. The device is configured to output a signal, for example to a synthesiser 52, loudspeaker 56 or headphones 54, for simulating the performance and may be subject to processing such as filtering, equalisation, amplification, noise reduction, compression and modulation. The device may be used by a player, when practising, to provide a quieter output than would be achieved by playing the instrument naturally. The mounting portion may comprise a mouthpiece which replaces the original mouthpiece of the instrument, and may include a passage for expelling air blown into it by a user. A pressure sensor preferably detects movement of air within the passage. An independent claim defines a blown musical instrument with a hollow body, means for transmitting and receiving a non-audible wave within the body, and means for outputting a signal. |
