The Prophet's ﷺ recitation was loud enough for one who was in the inner chamber to hear it when he was in the house.  

أبو داود:١٣٢٧ – حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ الْوَرْكَانِيُّ حَدَّثَنَا ابْنُ أَبِي الزِّنَادِ عَنْ عَمْرِو بْنِ أَبِي عَمْرٍو مَوْلَى الْمُطَّلِبِ عَنْ عِكْرِمَةَ عَنِ ابْنِ عَبَّاسٍ قَالَ

كَانَتْ قِرَاءَةُ النَّبِيِّ ﷺ عَلَى قَدْرِ مَا يَسْمَعُهُ مَنْ فِي الْحُجْرَةِ وَهُوَ فِي الْبَيْتِ

The Prophet's ﷺ recitation was loud enough for one who was in the inner chamber to hear it when he was in the house. (Using translation from Abū Dāʾūd 1327)   

أحمد:٢٤٤٦ – حَدَّثَنَا سُرَيْجٌ حَدَّثَنَا ابْنُ أَبِي الزِّنَادِ عَنْ عَمْرِو بْنِ أَبِي عَمْرٍو عَنْ عِكْرِمَةَ عَنِ ابْنِ عَبَّاسٍ قَالَ

كَانَتْ قِرَاءَةُ رَسُولِ اللهِ ﷺ بِاللَّيْلِ قَدْرَ مَا يَسْمَعُهُ مَنْ فِي الْحُجْرَةِ وَهُوَ فِي الْبَيْتِ
