​​ETS-Lindgren's Head and Torso Test (HATS) Enclosure provides a free-field environment for head and torso testing of mobile phones and other handheld audio devices. Our Head and Torso Test (HATS) Enclosure are an affordable option when a large anechoic chamber is not required. Testing can be conducted using a head and torso unit, a single microphone, or a small array of microphones. This enclosure has the ability to split into two halves without tools, and is designed to fit through a standard door opening, allowing for easy relocation.
