The audio file titled "March 3, 1973 - Section 3.3" commences with the gentle hum of ambient sound. It sets the scene in a classic 1970s barber shop, filled with the subtle chatter and laughter of the patrons. The audio further indulges the listener with the distinct, rhythmic snip-snip of scissors, occasionally interrupted by the low buzz of an electric razor. The sound of a soft sweep of a brush against the back of a neck suggests a finishing touch to a customer's haircut. The resonant ding of an old-fashioned cash register can be heard, signifying the end of a service. The overlay of these sounds creates a vivid soundscape, transporting the listener back to a bustling barber shop on March 3, 1973. The audio file ends with the fading murmurs of patrons and the distinctive jingle of the shop's door, indicating the departure of a satisfied customer.
