The market for binaural recording devices (HATS — Head and Torso Simulators) demonstrates paradoxical dynamics: prices are rising faster than technology is advancing. At first glance, the concept is trivial — two microphones placed in the "ears" of an artificial head should cost about as much as a pair of quality microphones. However, reality shows otherwise: costs range from several thousand to millions of rubles, comparable to the price of a used car.
The key factor forming the price is not so much the hardware component as acoustic precision and calibration. A HATS must reproduce anatomical features of human hearing, including interaural time and level differences, as well as frequency characteristics dictated by the shape of the ear canal and torso. Even minimal deviations in geometry or materials significantly affect the result, requiring complex engineering and precise measurements.
The price spread is explained by market segmentation: from hobbyist devices to professional laboratory setups. Between these poles, there are practically no intermediate solutions, creating a gap in technology accessibility. Manufacturers focus on niche tasks — from creating immersive content to scientific research — where precision becomes critical and compromises are unacceptable.
The importance of HATS is growing alongside the development of spatial audio, virtual reality, and metaverses. In these areas, the realism of the sound environment directly affects the user experience. Thus, high prices reflect not just the cost of components, but the value of precisely reproducing human sound perception — a resource that cannot be replaced by software emulation without losing quality.
