An onboard microphone (Telemike) was developed to examine changes in the basic characteristics of echolocation sounds of small frequency-modulated echolocating bats, Pipistrellus abramus. Using a dual high-speed video camera system, spatiotemporal observations of echolocation characteristics were conducted on bats during a landing flight task in the laboratory. The Telemike allowed us to observe emitted pulses and returning echoes to which the flying bats listened during flight, and the…

Compensation behaviors in echolocating bats measured by a telemetry microphone during flight

Some echolocating bat species are well known to compensate for the Doppler shifts in the echoes by changing their pulse frequencies so that the echo frequencies remain constant at which the bats can

Adaptive SONAR sounds by echolocating bats

Comparative studies between the field and laboratory recordings are expected to help the understanding of bat's biosonar system, and various echolocation strategies employed by the bats will contribute to develop artificial SONAR system or new echo-sensing devices in the future.

Mitigation of Signal Jamming in Bat Echolocation

This work discusses how bats extract own faint echoes in the presence of noise, by focusing on three similar but different situations; auditory masking, clutter interference, and jamming.

Echolocation behaviours of the Japanese pipistrelle batPipistrellus abramus during foraging flight

The acoustic structure of echolocation pulses emitted by Japanese pipistrellePipistrellus abramus (Temminck, 1840) bats during different phases of aerial hawking is described here for the first time.

On-board telemetry of emitted sounds from free-flying bats: compensation for velocity and distance stabilizes echo frequency and amplitude

Telemike recordings confirm that flying horseshoe bats (Rhinolophus ferrumequinum nippon) adjust the frequency of their sonar broadcasts to compensate for echo Doppler shifts.

Wireless recording of the calls of Rousettus aegyptiacus and their reproduction using electrostatic transducers

The ability to record and accurately synthesize echolocation calls enables the exploitation of biological signals in human engineering systems for sonar, materials characterization and imaging.

Scanning Behavior in Echolocating Common Pipistrelle Bats (Pipistrellus pipistrellus)

It is found that echolocating bats use a “saccade and fixate” strategy similar to vision, which is capable of finding and exploring targets in a wide search cone centered along flight direction.

Echolocation and flight strategy of Japanese house bats during natural foraging, revealed by a microphone array system.

These findings suggest that the bats confirm the presence of target prey by extending the duration of the pulse and then select a straight-ahead approach by forecasting the movement of the prey.

Intensity and directionality of bat echolocation signals

It is highlighted how multiple call parameters in unison define the search volume probed by bats and in turn how bats perceive their surroundings, facilitating successful navigation and food acquisition across a vast range of ecological niches.



Ultrasonic vocalizations of flying bats monitored by radiotelemetry.

A device light enough to be carried by an 11 g bat for periods of up to 1 h transmitted signals adequate for fine frequency analysis within a range of approximately 3 m, which allowed the recording of constant-frequency pulses free from flight-induced Doppler shifts and without time delays.

An electronic target simulator was used to produce artificial echoes for the echolocating bat, Rhinolophus ferrumequinum, and it changed the frequency of the constant‐frequency portions of its outgoing orientation sounds to restore the CF portions of returning echoes to the bat's preferred frequency.

Doppler-shift compensation in the Taiwanese leaf-nosed bat (Hipposideros terasensis) recorded with a telemetry microphone system during flight.

Biosonar behavior was examined in Taiwanese leaf-nosed bats (Hipposideros terasensis; CF-FM bats) during flight, finding bats in flight may periodically alter their attended angles from the front to the side when emitting echolocation pulses.

The echolocation and hunting behavior of the bat,Pipistrellus kuhli

The echolocation and hunting behavior of Pipistrellus kuhli was studied in the field using multi-exposure photography synchronized with high-speed tape recordings to argue that the minimum detection distance can be estimated from the pulse duration as the distance where pulse-echo overlap is avoided.

Sonar gain control and echo detection thresholds in the echolocating bat, Eptesicus fuscus.

The observed effect is operationally equivalent to forward masking of echoes by the transmission, but any events correlated with vocalization which impair hearing sensitivity for a short interval following transmissions could cause a decline in sensitivity to echoes.

Acoustic imaging in bat sonar: Echolocation signals and the evolution of echolocation

SummaryEcholocating bats behave as though they perceive the crosscorrelation functions between their sonar transmissions and echoes as images of targets, at least with respect to perception of target

Echolocation signals of the greater horseshoe bat (Rhinolophus ferrumequinum) in transfer flight and during landing.

It was confirmed that during flight the bats compensate the Doppler shifts which are produced by their own flight movement as well as the signal-echo overlap of the FM component, suggesting that the tFM component is used for ranging.

It is hypothesized that the bat's directional emissions, directional hearing, middle ear muscle contractions, and head aim response collectively create a three- dimensional spatial tracking filter which the bat locks onto targets to stabilize echo amplitudes during interception of prey.

Correlation analysis shows that, despite large changes in the duration of the pulses emitted by E. fuscus during an approach, the pulse frequency structure is such that the spatial image of the target perceived along the range axis is highly stable.

Intensity control during target approach in echolocating bats; stereotypical sensori-motor behaviour in Daubenton's bats, Myotis daubentonii.

It is concluded that intensity compensation does not rely on feedback information from received intensity, but instead follows a stereotyped pattern.
