Seismic waveform tomography with multicomponent data at a groundwater contamination site
… tomography, and applies it, together with traditional acoustic waveform tomography, to a multicomponent seismic data set acquired over a shallow contaminated aquifer at Hill Air Force Base, Utah. The study combines the high resolution provided by waveform tomography with inherent advantages …

Adaptive reception for underwater communications
… the radio channel is replaced by an underwater acoustic channel, which is strongly dependent on the physical properties of the ocean medium and its boundaries, the link geometry and the ambient noise. Traditional acoustic communications have involved a priori matching of the signaling parameters …

Programmable MIDI Instrument Controller Design: The No Strings Attached Hammer Dulcimer
… in real time. The controller emulates a traditional acoustic folk instrument known as a hammer dulcimer. The hammer dulcimer is the forerunner of the keyboard family of instruments and incorporates features found in percussive and keyboard instruments. As with any acoustic instrument, its …

Self-Supervised Learning for Speech Processing
… characteristics into a more accessible form than traditional acoustic features, and demonstrate their effectiveness in improving the performance of deep neural networks on a wide range of speech processing tasks. In addition to presenting new learning algorithms, we also provide extensive analysis …

Active structural acoustic control of aircraft interior flow noise via the use of active trim panels
… using the active panel are compared with more traditional acoustic control utilizing speakers as control actuators instead of PZT's. The project concludes that a 2 dB reduction over the frequency range is obtainable at the pilot's ears in a 2I20 configuration with an accelerometer reference …

Acoustic-based machine learning diagnostic tool for voice disorders
… the novel methods are presented, including deep acoustic recurrent model that combines frame-based cepstral and spectral features and Bi-directional Long short-term memory (Bi-LSTM) network, a 10-layer convolutional neural network (CNN) model with spectrogram of the speech as input, transfer …

Spontaneous Minds and Electric Romanticism: Kerouac, Ginsberg, Dylan, Joplin
… electric Romanticism. As opposed to its “acoustic” forebear, electric Romanticism exists in an electric age, beginning after Henry David Thoreau’s rumination on the telegraph wire as an electric rendering of the æolian harp image. Romantic poets used the æolian harp to analogize the act of …

Methods for pronunciation assessment in computer aided language learning
… using a variety of features derived from acoustic model scores and vowel class distributions. We confirm that the transformation technique results in a more robust and accurate identification of mispronunciations than traditional acoustic models.

The potential of LIDAR as an antisubmarine warfare sensor
Traditionally, antisubmarine warfare (ASW) has been dominated by acoustic sensors, active and passive. Ending the Cold War, the ASW forces have refocused towards a theatre of war in the littorals, and the traditional acoustic sensors do not perform very well in such an environment. The sensors are …

Creative Intuition as a Compositional Strategy in Electroacoustic Music
… The compositional manipulation of time in electroacoustic music could be seen to present different challenges to the composer than those of traditional acoustic music. In considering the poetics of time in electroacoustic music I have used Sin Ti Par EI Alma Adentro as a starting point for my …

Música Tejana and the Transition from Traditional to Modern: Manuel “Cowboy” Donley and the Austin Music Scene
… music rooted in la canción mexicana, used acoustic instruments. The first Música Tejana ensembles to “go electric” originated a new music scene and experienced the transition from acoustic to electric and the separation of ensemble instrumentation into the categories of modern electric and …
