Editing Microbat (section)

=== Production of ultrasonic waves ===
Most microbats generate ultrasound with their larynx and emit the sound through their nose or mouth.<ref>{{Cite journal|last1=Hedenström|first1=Anders|last2=Johansson|first2=L.

Vocalization requires these elastic membranes because they act as a source to transform airflow into acoustic pressure waves. Energy is supplied to the elastic membranes from the lungs, and results in the production of sound. The larynx houses the [[Vocal folds|vocal cords]] and forms the passageway for the expiratory air that will produce sound.<ref>{{Cite journal|last1=Holbrook|first1=K A|last2=Odland|first2=G F|date=1978-05-01|title=A collagen and elastic network in the wing of the bat.|journal=Journal of Anatomy|volume=126|issue=Pt 1|pages=21–36|issn=0021-8782|pmc=1235709|pmid=649500}}</ref> Microbat {{Audio|Ultrasonic_bat_calls.ogg|calls}} range in frequency from 14,000 to over 100,000 [[hertz]], well beyond the range of the human ear (typical human hearing range is considered to be from 20 to 20,000&nbsp;Hz). The emitted vocalizations form a broad beam of sound used to probe the environment, as well as communicate with other bats. At the molecular level, it has been found that [[CPLX1]] is involved in this ultrasonic wave production.<ref>{{Cite journal |last1=Liu |first1=Meiling |last2=Wang |first2=Changliang |last3=Huo |first3=Lifang |last4=Cao |first4=Jie |last5=Mao |first5=Xiuguang |last6=He |first6=Ziqing |last7=Hu |first7=Chuanxia |last8=Sun |first8=Haijian |last9=Deng |first9=Wenjun |last10=He |first10=Weiya |last11=Chen |first11=Yifu |last12=Gu |first12=Meifeng |last13=Liao |first13=Jiayu |last14=Guo |first14=Ning |last15=He |first15=Xiangyang |date=July 2024 |title=Complexin-1 enhances ultrasound neurotransmission in the mammalian auditory pathway |url=https://www.nature.com/articles/s41588-024-01781-z |journal=Nature Genetics |volume=56 |issue=7 |pages=1503–1515 |doi=10.1038/s41588-024-01781-z |pmid=38834904 |issn=1546-1718}}</ref>
