Methods for making spatial microphone subassemblies, recording system and method for recording left and right ear sounds for use in virtual reality playback

A sound field recording system comprising:

• a paired acoustic pressure sensor assembly including a left side pressure sensor and a right side pressure sensor, said pressure sensor assembly being configured to be worn by a recording user or wearer with said left side pressure sensor and said right side pressure sensor being oriented and aimed from the respective left and right sides of a wearer's head, on or proximate the wearer's left and right temples, and suspended in front of the wearer's ears, when recording;
• wherein each of said left side pressure sensor and a right side pressure sensor comprises a miniature solid state transducer affixed within a substantially rigid and hollow housing member;
• wherein each of said left side pressure sensor housing member and said right side pressure sensor housing member is carried on the distal end of a cable temple defining ear hook member made from a segment of malleable material configured to be shaped by the wearer to fit over an ear to position one of the sensor housing members next to each of the wearer's temples, in front of the ear canal and in front of the tragus, when in use;
• and
• wherein each of said left side pressure sensor and a right side pressure sensor comprises a miniaturized solid state electret microphone affixed within a substantially spherical hollow housing member defining a lumen therethrough with opposing open ends;
• and
• wherein each of said left side pressure sensor housing member and said right side pressure sensor housing member is configured with said miniature solid state transducer affixed within a substantially rigid hollow tube segment which is enclosed within a hollow 10-14 mm sphere made of nylon or a similar dense non-resonant material.
