It is recommended to raise the voice in the sermon so that it reaches as far as possible, while noting the loudspeakers that are outside the mosque.

The Shaykh : One of the benefits of this hadith is that it is recommended to raise the voice in the sermon so that it reaches as far as possible. What is the evidence? That the Prophet (peace and blessings be upon him) raised his voice with it. Based on this, we say that the loudspeaker in mosques, schools, and other required matters is required because it is used to convey the sermon and convey knowledge as far as possible.
But here is an issue that we must point out, which is that some people in their mosques pray and turn on the sound on the speakers in the minaret, which causes disturbance to nearby mosques and to the people in their homes. This is a mistake; they are closer to sin than to safety. They are closer to sin than to safety. Why? Because disturbing your Muslim brothers is harming them without a doubt; you are harming them. In fact, we have heard of a mosque where their imam was praying, and the imam's recitation was not very good, and around them was a mosque praying with a microphone where the imam's recitation was good. So when the nearby mosque's imam said, "And not the astray," these people said, "Ameen." The imam was confused: why "Ameen"? Because they heard what? The recitation of the second mosque. Then, if we assume that the people in the second mosque are prostrating, and this one is reciting, he disturbs them, and they do not know what to say in their prostration or bowing.
