Valmiki Ramayana Ayodhya Kanda Sarga 51 Shloka 13

स्त्रियः women, सुमहानादम् loud sound, विनद्य having raised, श्रमेण because of exhaustion, उपरताः ceased, अतः for that reason, राजनिवेशनम् king's palace, निर्घोषोपरतम् sounds have ceased, मन्ये I consider.

All the women having cried so much must have quietened down out of sheer exhaustion. That is why perhaps the sounds from the royal palace have ceased.
