James A. Simmons spends much of his time researching Acoustics, Sonar, Human echolocation, Eptesicus fuscus and Echo. His study in Acoustics is interdisciplinary in nature, drawing from both Vertical direction and Remote sensing. The concepts of his Sonar study are interwoven with issues in Ultrasonic sensor, Ranging, Optoacoustic imaging and Spectrogram.
His Human echolocation research is multidisciplinary, relying on both Sound localization and Communication. The various areas that James A. Simmons examines in his Eptesicus fuscus study include Amplitude, Auditory system, Neuroscience and Phyllostomus hastatus. His work carried out in the field of Echolocation jamming brings together such families of science as Ecology, Predation, Absorption and Movement.
The scientist’s investigation covers issues in Acoustics, Sonar, Human echolocation, Eptesicus fuscus and Echo. The study incorporates disciplines such as Clutter and Interference in addition to Acoustics. His Clutter research includes themes of Speech recognition and Masking.
The Sonar study combines topics in areas such as Auditory system, Bandwidth and Computer vision. His work in the fields of Human echolocation, such as Echolocation jamming, overlaps with other areas such as Pulse. His Eptesicus study in the realm of Eptesicus fuscus interacts with subjects such as Target range.
James A. Simmons mainly investigates Acoustics, Sonar, Human echolocation, Eptesicus fuscus and Clutter. His work on Noise as part of his general Acoustics study is frequently connected to Echo, Microphone and Ambiguity, thereby bridging the divide between different branches of science. His Sonar research includes elements of Perspective, Cochlea and Gaze, Computer vision.
James A. Simmons interconnects Stimulus, Seismology, Culvert and Harmonic in the investigation of issues within Human echolocation. His work deals with themes such as Noise, Sound pressure, Inferior colliculus, Sound exposure and Local field potential, which intersect with Eptesicus fuscus. James A. Simmons works mostly in the field of Clutter, limiting it down to topics relating to Sound and, in certain cases, Range and Speech recognition.
James A. Simmons mainly focuses on Human echolocation, Eptesicus fuscus, Acoustics, Sound exposure and Sonar. His studies in Human echolocation integrate themes in fields like Perspective, Sensory system, High spatial resolution and Eye movement, Artificial intelligence. His work on Noise as part of general Acoustics study is frequently linked to Pulse and Echo, therefore connecting diverse disciplines of science.
His studies examine the connections between Noise and genetics, as well as such issues in Bioacoustics, with regards to Sensitivity, Wideband and Psychoacoustics. His Sound exposure study also includes fields such as
