Is there an aural chime heard in the cabin when the PA button is pressed on the ERJ 175?

When the PA (Public Address) button is pressed on the ERJ 175, there is no aural chime heard in the cabin. This design choice helps to keep the cabin environment relatively calm and allows the flight attendants to make announcements without a preemptive chime, ensuring that the message from the crew can be clearer and more direct. The absence of a chime indicates to the crew that they can speak as needed without an alerting sound, streamlining communication in the aircraft. This functionality is consistent across all ERJ 175s and does not vary by individual aircraft, which maintains operational consistency and ease of use for the flight crew.
