Anechoic chambers are incredibly quiet , most people report being able to hear the normally inaudible sounds of their own bodies while in them; like their heart beat.
I am currently doing an art project that involves sound-proofing a room to turn it into a DIY anechoic chamber. I was wondering if anyone has advice about the cheapest/easiest way of achieving this level of sound proofing?
Sure it would be expensive, but some of y'all spend huge amounts of money on speakers, amps, turntables, and even cables. It seems to me that building an anechoic chamber, or something reasonably close to one, would be the ultimate "room treatment" for the listening room of a true audiophile.
I went down an internet rabbit hole the other day and found out about anechoic chambers. Some googling suggests SFU has one but I couldn't find much else. Has anyone been and or know how one could visit it?
Summary of Publication:
> This engineering brief describes the design, construction and validation of a low-cost acoustic anechoic chamber. This anechoic chamber will be used in a production setting as well as for research and development of a microphone array system. Three chambers have been built using the same method. The performance of the rooms is evaluated in terms of sound isolation, deviation from inverse square law, frequency response function and reverberation time. Results show that in the frequency range of interest (250 - 11025 Hz), the reverberation time for the three chambers is 19 ± 3 ms. The difference between the frequency response of the chambers is ± 4 dB in the frequency range of interest for the two latest built chambers, whereas the ?rst chamber shows a larger deviation.

I am using an anechoic chamber for undergraduate research to take measurements of a headset that will transmit to a horn antenna receiver. A question I have is will rotating the receiver along the azimuth take the same measurements as rotating the transmitter? I have been told it will, but I can’t really visualize how that is true. Thank you :)
I just watched a video about the anechoic chamber making people crazy. I genuinely feel like this must be malarkey, at least a little. I'd like to hear how deaf people who have read about this chamber feel.
