The sound of a fighter jet aircraft as it takes off or flies by at high power is unique, in part, because of “crackle.”
2aSC3 – Studying Vocal Fold Non-Stationary Behavior during Connected Speech Using High-Speed Videoendoscopy
The most sophisticated tool for laryngeal imaging is high-speed videoendoscopy, which enables us to record vocal fold vibrations with high temporal resolution.
2aBAb2 – Feasibility of using ultrasound with microbubbles to purify cell lines for immunotherapy application
Cells are isolated and sorted for a variety of diagnostic (e.g., blood tests) and therapeutic (e.g., stem cells, immunotherapy) applications, as well as for general research.
researchers deployed two autonomous marine acoustic recorders (AMAR) in Haro Strait (BC), from July to October 2017, to measure sound levels produced by large merchant vessels transiting the strait.
One set of difficult sounds is called the sibilants, an example of which is /s/. Polish has a complex three-way sibilant contrast
Researchers trained the algorithm by showing it ultrasound images collected from over 70 pediatric and adult patients.
In this study, bottlenose dolphins were trained to “whistle” upon hearing a computer-generated tone
In the quest for a meaningful message to pass to these young end users, this article introduces a new metric, the “Age of Your Ears” (AYE), that is an indication of the predicted extra aging caused by the excessive noise dose each user is exposed to.
While several techniques are available for seabed characterization via acoustic remote sensing, this is a first demonstration using noise from a large ship-of-opportunity (i.e., a passing ship with no connection to an experiment).
1a2b3c – How bowhead whales cope with changes in natural and anthropogenic ocean noise in the arctic
Previous work by researchers has found that bowhead whales double their calling rate whenever distant seismic signals are present
Rather than “shouting” above this ambient noise with powerful dedicated sound sources, we are now learning how to measure ocean currents and seafloor properties using the noise itself.
This “OLED Panel Speaker” was developed by attaching exciters on the back of OLED panels, which do not have backlights.
Because our ears are always “on”, our auditory system receives a lot of input to process. But, what can we “hear” when we are asleep?
Towards the goal of both listening to the fish and identifying which species are vocalizing, researchers developed a Fish Optical and Acoustic Sensor Identification System (FishOASIS)
Ultrasound plays a pivotal role in the life of bats, since the animals rely on echoes triggered by their ultrasonic biosonar pulses as their primary source of information on their environments.
Experiments have shown that the wooden parts of the piano can produce sounds that are not created in the string. That is, the wood can be a source of sound as well as the string, and it is not always simply a filter.
From the yanny or laurel phenomenon, it should be clear that what we perceive is dependent not only upon the physics of the world around us, but also upon our individual anatomy and individual life experiences.
2pAB8 – Blind as a bat? Evidence suggests bats use vision to supplement echolocation in presence of ambient light
Previous studies have demonstrated that vision in bats influences flight behavior, which suggests bats may combine vision and echolocation to sense their environment
Myopia, or near-sightedness, affects up to 2.3 billion people and has a high prevalence. Although minimal levels of myopia are considered a minor inconvenience, high myopia is associated with sight-threatening pathology in 70% of patients
The biomechanical modeling platform Artisynth allows scientists to study realistic 3D models of the vocal tract
Many specialty fitness centres have been proactive in ensuring they meet the appropriate noise standards by seeking support from acousticians.
2aAA8 – Nature as Muse: The characteristics of caves can help us add an individual touch to our music
Researchers sought to explore nature as architect and to demonstrate how incorporating the characteristics of these distinct structures can make a meaningful contribution to the audio engineer’s creative palate
While visual graphics in Virtual Reality (VR) systems are very well developed, the manner in which acoustic environments and sounds may be recreated in a VR system is not.
when stressed, the European lobster produces a species-specific sound that we call a “buzz”
moving vehicles and the moored station construct a triangular formation which can be used to map the ocean currents.
For the past several years, researchers have been working to better understand the effect that vessel traffic and underwater noise is having on individual killer whales.
1pSCb15 – Why your boot might not sound like my boot: Gender, ethnicity, and back-vowel fronting in Mississippi
Back-vowel fronting is a particular type of pronunciation change that affects American English vowels like the /u/ in boot and the /o/ in boat.
Researchers examine underwater acoustic data that collected in the western Canadian Arctic, and when four species of marine mammals were vocalizing.
5aSP2 – Two-dimensional high-resolution acoustic localization of distributed coherent sources for structural health monitoring
This work shows that yes, it is possible to localize defects using only acoustic measurements, and such a technique is validated with two proof-of-concept experiments.
What do adult voice actors do with their vocal tracts in order to sound like a child?
1aPAb1 – On the origin of thunder: reconstruction of lightning flashes, statistical analysis and modeling
Dating the lighting ground impact and therefore the emission time, the detailed position of each noise source within the lightning flash can be reconstructed.
2pSC34 – Distinguishing Dick from Jane: Children’s voices are more difficult to identify than adults’ voices
children’s voices differ substantially from adults, arising from differences in the size of their vocal tracts, to how well they can control their articulators (e.g., tongue) to form speech sounds, to differences in their linguistic knowledge
Overcoming challenges will allow the application of ecoacoustic monitoring to a broad range of conservation and ecological research questions
The Lombard effect is when speakers unconsciously increase the loudness level of their speech in the presence of background noise in order to be understood.
Acoustic monitoring of drum fish spawning revealed that they are extremely productive, spawning every day of the spawning season
In order to predict and model the distances over which any acoustic ocean monitoring, detection, or communication systems may operate, accurate knowledge of the acoustic properties of the seabed must be known.
Researchers are trying to change the way kidney stones are managed.
