The primate 'talks' with ultrasound

AFP quoted a study by US and Philippine scientists published on February 8, saying that one of the world's smallest primates Tarsius syrichta communicates with each other with ultrasound that we cannot hear. even when near them.

According to research reports, the primates are no bigger than a man's hand.

Tarsius syrichta can listen to and emit regular sounds with effective frequencies to alert the danger. This is also one of the only mammals that can send and receive ultrasonic sound signals at frequencies of more than 20 kilohertz (kHz).

Compared to humans, primates catch the ultrasonic signal 'signal' better. Humans cannot hear sounds above 20 kHz while dogs can hear whistles ranging in frequency from 22 to 23 kHz.

The world's smallest primate 'talks' with ultrasound.

In order to measure the frequency of primates of primates, scientists have recorded 35 samples in nature.

According to scientists, the maximum frequency of vocalization reaches 67 kHz, which is the highest value of any terrestrial mammal, both bats and some rodents.

The sound of ultrasound can be advantageous for both the emitting signal and the child receiving the signal, especially making it difficult for predators to detect and locate.

The world's smallest primates have five fingers that resemble humans and the largest eyes of any other primates that live in nature.
