The phrase "acoustic characters" is correct and usable in written English.
It can be used in contexts related to sound, music, or phonetics, referring to the qualities or features of sound that are produced acoustically.
Example: "The study focused on the acoustic characters of different musical instruments to understand their unique sound profiles."
Alternatives: "sound qualities" or "acoustic features".
Our results support studies that have suggested captivity may impact acoustic characters of USVs [5], particularly variability and pitch.
To understand the changes in male acoustic signals in response to the broadcast stimulus, I developed a multivariate general linear model (GLM) for five acoustic characters.
Acoustic characters were obtained from recordings of living fishes.
However, variation in most acoustic characters is quantitative rather than categorical.
While these systems may act in low-duty cycle echolocation, Kingston et al.[ 33] argued that divergence in acoustic characters is more likely to cause fast reproductive isolation in high-duty cycle echolocation where selection for mate recognition within phonic groups is reinforced by postnatal tuning of the auditory fovea forming a positive feedback loop.
Acoustic characters were optimized in two data sets (1) with of all cetacean species and (2) pruning species that are known not to emit tonal sounds, species for which acoustic behavior is poorly known, and species that are known to produce tonal sounds but for which detailed information for the character under study was not available.
The system of syllable quantity, connected with that of vowel length, must have given Classical Latin distinctive acoustic character.
Furthermore, the continuity of five gently dipping fractured structures that contain a few sections of broken rock between the 1-km-deep holes drilled approximately 0.5 km apart is suggested according to similarities in the acoustic character in the full waveform sonic borehole logs.
This can be accomplished by covering all surfaces with deep absorptive wedges, which gives the chambers a distinct acoustic character and an unmistakable visual presence.
In support of the latter hypothesis, there is at least one documented case of likely acoustic character displacement for horseshoe bat call frequencies [20].
To test for acoustic character displacement in sympatric populations we compared the average acoustic distances between both species (excluding the sympatric populations) with those at the sympatric Nairobi site.
