Background A small number of blind people are adept at echolocating silent objects simply by producing mouth clicks and listening to the returning echoes. Yet the neural architecture underlying this type of aid-free human echolocation has not been investigated. To tackle this question, we recruited echolocation…

'Graeme E. Smith' 'Zeng Tao' 'Raja Syamsul Azmir Bin. Raja Abdullah' 'Mikhail Cherniakov' 'Christopher J. Baker' 'Daniel Kish' 'Michail Antoniou' 'Frédéric E. Theunissen'] Echolocation is the ability to use sound-echoes to infer spatial information about the environment. Some blind people have developed extraordinary…

Echolocation enables blind individuals to perceive and navigate their environment by emitting clicks and interpreting their returning echoes. While expert blind echolocators demonstrate remarkable spatial accuracy, the behavioral and neural mechanisms supporting the temporal integration of spatial echoacoustic cues…

Blindness imposes constraints on the acquisition of environmental sensory information. To mitigate those constraints, some blind people employ active echolocation, a technique in which self-generated tongue “clicks” produce informative reflections from surrounding surfaces. Practitioners typically produce multiple…

'M. C. J. Hornikx'] Some people who are blind have trained themselves in echolocation using mouth clicks. Here, we provide the first report of psychophysical and clicking data during echolocation of distance from a group of 8 blind people with experience in mouth click-based echolocation (daily use for > 3 years). We…

'Piotr Skulimowski' 'Paweł Strumiłło' 'Abel C.H. Chen'] Echolocation is a vital method of spatial orientation for many visually impaired individuals who are willing to and able to learn it. Blind echolocators use a variety of sounds, such as mouth clicks, cane taps, or specialized sound-emitting devices, to perceive…

Many blind people rely on echoes from self-produced sounds to assess their environment. It has been shown that human subjects can use echolocation for directional localization and orientation in a room, but echo-acoustic distance perception - e.g. to determine one's position in a room - has received little scientific…

Human echolocation describes how people use reflected sounds to obtain information about their ambient world. We investigated, by using auditory models, how three perceptual parameters, loudness, pitch and sharpness, determine echolocation. We used acoustic recordings from two previous studies, both from stationary…

'Shizuko Hiryu' 'Hiroshi Ando' 'Mounya Elhilali'] Bats use echolocation through flexible active sensing via ultrasounds to identify environments suitable for their habitat and foraging. Mimicking the sensing strategies of bats for echolocation, this study examined how humans acquire new acoustic-sensing abilities, and…

Bats use a sophisticated ultrasonic sensing method called echolocation to recognize the environment. Recently, it has been reported that normal sight participants with no prior experience in echolocation can improve their ability to perceive the spatial layout of various environments through training to hear echoes…

People can learn new sensory skills that augment their perception, such as human echolocation. However, it is not clear to what extent these can become an integral part of the perceptual repertoire. Can they show automatic use, integrated with the other senses, or do they remain cognitively-demanding, cumbersome, and…

'Adam Scholefield' 'Martin Vetterli'] Abstract—For safe and efficient operation, mobile robots need to perceive their environment, and in particular, perform tasks such as obstacle detection, localization, and mapping. Although robots are often equipped with microphones and speakers, the audio modality is rarely used…

Echolocating bats locate the targets by echolocation. Many theoretical frameworks have been suggested the abilities of bats are related to the shapes of bats ears, but few artificial bat-like ears have been made to mimic the abilities, the difficulty of which lies in the determination of the elevation angle of the…

Active sensing animals perceive their surroundings by emitting probes of energy and analyzing how the environment modulates these probes. However, the probes of conspecifics can jam active sensing, which should cause problems for groups of active sensing animals. This problem was termed the cocktail party nightmare for…

Echolocation is the prime sensing modality for many species of bats, who show the intricate ability to perform a plethora of tasks in complex and unstructured environments. Understanding this exceptional feat of sensorimotor interaction is a key aspect into building more robust and performant man-made sonar sensors. In…

Spatial hearing allows humans to localize sound sources in the azimuth plane using interaural time (ITD) and level (ILD) differences, but the contribution of additional auditory features remains unclear. To investigate this, we measured human localization performance with natural and artificial stimuli that selectively…
