The phrase "acoustical techniques" is correct and usable in written English.
It can be used when discussing methods or approaches related to sound, acoustics, or audio engineering.
Example: "The researchers employed various acoustical techniques to enhance the quality of the recorded sound."
Alternatives: "audio methods" or "sound techniques".
Among these, broad ranging acoustical techniques have revealed diverse fish populations and their distribution, while direct, close up observation made possible by deep-sea submersibles has resulted in the discovery of unusual (and unexpected) species and phenomena.
The resonance characteristics of second-sound waves in liquid helium II are analyzed by using standard acoustical techniques.
The new devices not only portray the surface of the skin, but also use a variety of optical and acoustical techniques to virtually "punch holes" in hundreds of cells deep within the human body, while using contrast agents to identify abnormalities.
Munk solved the mystery of why one side of the moon always faces the earth in its rotation, showed that Alaska's waves (and in the summer San Diego's) mostly start in Antarctica, pioneered advanced acoustical techniques to provide information about how the deep sea works, and discovered the ways winds shape currents, encapsulated in his phrase "wind-driven gyres".
Rapid advancements in acoustical beamforming techniques for array signal processing are producing algorithms with increased levels of computational complexity.
Associated to acoustical imaging techniques, it allows the construction of sound radiation movies that evolve within the engine cycle and whose each frame is a sound intensity map calculated at a specific time – or crankshaft angle – in the engine cycle.
This paper applies the acoustical wave propagator technique to wave packet propagation in a one-dimensional stepped beam.
We have developed a specially designed sensor with its associated instrumentation using a so called acoustical near-field technique based on small resonating horns.
This paper presents the acoustical wave propagator technique to describe the flexural wave propagation and scattering in an elastic plate with multiple cylindrical patches.
This paper presents an explicit acoustical wave propagator technique to investigate the flexural wave scattering and dynamic stress concentration in a ribbed plate based on Mindlin plate theory.
The time-domain analytical solutions of this structure subjected to an initial-value problem with the specific Gaussian waveform were derived and compared with the predicted results obtained by the acoustical wave propagator technique.
