Optical Measurement of Acoustic Drum Strike Locations
نویسندگان
چکیده
This paper presents a method for locating the position of a strike on an acoustic drumhead. Near-field optical sensors were installed underneath the drumhead of a commercially available snare drum. By implementing a time difference of arrival (TDOA) algorithm, accuracy within 2cm was achieved in approximating the location of strikes. This method could be used for drum performance analysis, timbre analysis and can form a basis for an augmented drum performance system.

Design and Application of a Photoacoustic Sensor for Monitoring the Laser Generated Stress Waves in Optical Fiber
Measurement of stress transients generated by a 400ns pulsed HF laser in an infrared fluoride glass fiber has been made using fast time – response piezoelectric film transducer. Acoustic signals up to 12 mV with frequencies ranging in megahertz generated by 21 mJ laser pulse when passed through the fiber axis in the linear region. It is shown that useful information such as onset of non - linea...
متن کاملThe XY Drum
Standard electronic drum pads are equipped with one piezoelec tric sensor that converts stick strikes to electronic pulses which are measured and used to trigger pre-recorded samples or other sounds. Advanced models can measure the amplitude of this pulse and adjust the volume of the resultant sample or even select a different sample en tirely. The state of the art electronic drums are equipp...
متن کاملDrum Sound Detection in Polyphonic Music with Hidden Markov Models
This paper proposes a method for transcribing drums from polyphonic music using a network of connected hidden Markov models (HMMs). The task is to detect the temporal locations of unpitched percussive sounds (such as bass drum or hi-hat) and recognise the instruments played. Contrary to many earlier methods, a separate sound event segmentation is not done, but connected HMMs are used to perform...
متن کاملStrike-A-Tune: Fuzzy Music Navigation Using a Drum Interface
Project Goals • "Fuzzy" Navigation • Physically and Visually Intuitive • Large Libraries A traditional music library system controlled by a mouse and keyboard is precise, allowing users to select their desired song. Alternatively, randomized playlist or shuffles are used when users have no particular music in mind. We present a new interface and visualization system called Strike-A-Tune for fuz...
متن کاملAcoustic-Laser Vibrometry for Standoff Detection of Defects in Materials
Standoff methods of non-destructive testing (NDT) offer flexibility over traditional methods of inspection which typically require physical contact with the material being measured. The benefits are that difficult to access locations can be inspected and measurements of a large area can be made more quickly. Acoustic-laser vibrometry is a robust standoff NDT technique for composite materials, s...
