A collection of three electronic components:
2019.ph.845.1-2: Two similar microphone array boards. These are green PCB boards with serial ports at both narrow ends. An array of microphone components along one side, and a grey plastic mounting bracket at the opposite side. 2019.ph.845.1 has one microphone detached. 2019.ph.845.2 has a microchip taped to the plastic mounting bracket.
2019.ph.845.3: A power supply/ transmitter drive unit. This is an electronic enclosure, painted pale grey, with a series of ports and jacks on the front panel. The front panel also has a power switch and a red indicator light in the top left corner. There is an AC jack on the rear side.
Accession Number: 2019.ph.845.1-3
Alternative Name:
Primary Materials: Metal, Plastic.
2019.ph.845.1 and 2 have the following text printed on the surface: “UNIVERSITY OF TORONTO// DEPARTMENT OF PHYSICS// P87-A”
2019.ph.845.1 has a “2” written on the mounting bracket.
2019.ph.845.3 has a label on its front panel that reads “Unit #2// U. G. LAB”
2019.ph.845.1 and 2: Height = 2.5, Width = 13, Length = 32.5; 2019.ph.845.3: Height = 13.5, Width = 5.5, Length = 26.5.
This equipment is part of a larger apparatus meant to demonstrate acoustical refection.
This is a relatively small portion of the full acoustic reflection apparatus. Missing are a full set of microphone array boards, a computer, a large frame for the apparatus, and a set of plate models. 2019.ph.845.2 has one of its microphones detached. 2019.ph.845.3 has minor scratches and marks on its surface.
