 Acoustic Design & Sound System Checklist BY NOISE <\/strong><\/p>\n\n\n\n

A practical suggestion by <\/em>NOISE<\/em><\/strong> for architects, builders, committees, and consultants designing mosques, churches, prayer halls, and conference rooms.<\/em><\/p>\n\n\n\n

1. Early Planning (Before Construction)<\/strong><\/p>\n\n\n\n

    \n
  • Define room purpose: speech-only, prayer\/sermon, mixed speech & music<\/li>\n\n\n\n
  • Estimate occupancy and seating layout<\/li>\n\n\n\n
  • Determine target Reverberation Time (RT60)<\/strong>\n
      \n
    • Small\u2013medium prayer rooms: 0.8\u20131.2 sec<\/li>\n\n\n\n
    • Large mosques \/ churches: 1.2\u20131.8 sec (speech-focused)<\/li>\n\n\n\n
    • Conference rooms: 0.6\u20131.0 sec<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Involve an acoustic consultant early<\/li>\n<\/ul>\n\n\n\n

      2. Architectural Geometry<\/strong><\/p>\n\n\n\n

        \n
      • Avoid long, parallel walls (introduce angles or breaks)<\/li>\n\n\n\n
      • Control domes and concave surfaces (segment or treat acoustically)<\/li>\n\n\n\n
      • Use stepped or faceted ceilings instead of flat slabs<\/li>\n\n\n\n
      • Avoid sound-focusing corners and niches near speaker positions<\/li>\n<\/ul>\n\n\n\n

        3. Surface Materials (Core of Echo Control)<\/strong><\/p>\n\n\n\n

        Absorptive Materials<\/strong><\/p>\n\n\n\n

          \n
        • Acoustic wall panels (fabric-wrapped \/ perforated)<\/li>\n\n\n\n
        • Mineral wool or glass wool behind perforated boards<\/li>\n\n\n\n
        • Carpets or prayer mats (important for mid\u2013high frequency absorption)<\/li>\n\n\n\n
        • Acoustic ceiling tiles or baffles<\/li>\n<\/ul>\n\n\n\n

          Diffusive Elements<\/strong><\/p>\n\n\n\n

            \n
          • Wooden diffusers<\/li>\n\n\n\n
          • Bookshelves \/ patterned wall elements<\/li>\n\n\n\n
          • Geometric wall reliefs<\/li>\n<\/ul>\n\n\n\n

              Avoid overuse of marble, glass, tiles, and bare concrete without treatment<\/p>\n\n\n\n

            4. Ceiling Design<\/strong><\/p>\n\n\n\n

              \n
            • Use suspended acoustic ceilings where possible<\/li>\n\n\n\n
            • In high domes: apply ring absorbers or acoustic clouds<\/li>\n\n\n\n
            • Avoid fully reflective curved ceilings above speaker or imam area<\/li>\n<\/ul>\n\n\n\n

              5. Columns, Windows & Openings<\/strong><\/p>\n\n\n\n

                \n
              • Treat large columns with partial absorption<\/li>\n\n\n\n
              • Use heavy curtains on large windows if possible<\/li>\n\n\n\n
              • Seal unnecessary openings that leak sound or create flutter echo<\/li>\n<\/ul>\n\n\n\n

                6. Loudspeaker & PA System Planning<\/strong><\/p>\n\n\n\n

                  \n
                • Design speaker layout with the room<\/strong>, not after construction<\/li>\n\n\n\n
                • Prefer distributed speaker systems over single high-power sources<\/li>\n\n\n\n
                • Mount speakers to aim at listeners, not walls or ceilings<\/li>\n\n\n\n
                • Use delay speakers in long halls<\/li>\n\n\n\n
                • Avoid excessive volume to compensate for poor acoustics<\/li>\n<\/ul>\n\n\n\n

                  7. Electronics & Signal Processing<\/strong><\/p>\n\n\n\n

                    \n
                  • Use Digital Signal Processing (DSP) for:\n
                      \n
                    • Equalization (EQ)<\/li>\n\n\n\n
                    • Time alignment (delay)<\/li>\n\n\n\n
                    • Feedback control<\/li>\n<\/ul>\n<\/li>\n\n\n\n
                    • Match microphones to room size and usage<\/li>\n\n\n\n
                    • Avoid cheap microphones in highly reverberant spaces<\/li>\n<\/ul>\n\n\n\n

                      8. Testing & Commissioning<\/strong><\/p>\n\n\n\n

                        \n
                      • Measure actual RT60 after installation<\/li>\n\n\n\n
                      • Conduct speech intelligibility testing (STI)<\/li>\n\n\n\n
                      • Walk-test coverage consistency<\/li>\n\n\n\n
                      • Fine-tune EQ and delays on site<\/li>\n<\/ul>\n\n\n\n

                        9. Common Mistakes to Avoid<\/strong><\/p>\n\n\n\n

                          \n
                        • Installing sound systems without acoustic treatment<\/li>\n\n\n\n
                        • Increasing volume to fight echo<\/li>\n\n\n\n
                        • Copying designs from visually similar but acoustically different buildings<\/li>\n\n\n\n
                        • Ignoring acoustics during renovation<\/li>\n<\/ul>\n\n\n\n

                          10. When to Call Professionals<\/strong><\/p>\n\n\n\n

                            \n
                          • Large-capacity halls (>300 people)<\/li>\n\n\n\n
                          • Domed or architecturally complex spaces<\/li>\n\n\n\n
                          • Persistent echo despite good equipment<\/li>\n\n\n\n
                          • Renovation of heritage or existing buildings<\/li>\n<\/ul>\n\n\n\n

                            Final Note from NOISE<\/strong><\/p>\n\n\n\n

                            Good sound is not only about equipment \u2014 it is the result of architecture, materials, and scientific design working together<\/strong>. Investing in proper acoustic planning ensures clarity, comfort, and dignity in worship and communication.<\/p>\n\n\n\n

                            NOISE specializes in Retail Music Systems and Public Address Solutions for prayer halls, conference rooms, and public spaces \u2014 helping sound serve its true purpose: to be clearly heard. <\/em><\/strong><\/p>\n\n\n\n
