The audio begins with a soft, yet clear, 'ding' sound, immediately painting a picture of someone pressing a button on an entry phone. This is the 'Entry Phone for PRU.' Following the ding, a 'cshhh' sound resonates, adding a layer of static noise, suggesting the activation of the intercom system. The static continues, maintaining a constant, soft underlay throughout the audio. It evokes a sense of anticipation for communication to commence through this entry phone system. Amidst the static, there is a sudden, distinct, 'dong' sound, signifying that the line has been opened and someone on the other side is now ready to interact. The combination of these sounds - the initial 'ding', the constant 'cshhh' of static and the final 'dong', successfully generates an atmosphere of readiness for a conversation to begin over the entry phone for PRU.
