In 1997, Turkish audio engineer Ahmad Tekin Topuzdag went to Madinah for Umrah and noticed that the sound inside Masjid an-Nabawi was unclear, with too much echo and feedback.

He spoke to the mosque’s management and was given one section to test his ideas. The improvement was so noticeable that he was asked to help fix the entire sound system.

Over the next 10 years, he completely upgraded the audio system at Masjid an-Nabawi and also worked on the sound system at Masjid al-Haram. He replaced microphones, cables, speakers and other equipment, adjusted the system for each Imam and muezzin, reduced echo and feedback, and divided the mosque into seven audio zones.

He also added microphones so the Imam could be heard clearly during every part of the prayer.

After finishing the work, the sound became much clearer and covered a much wider range of frequencies. Before leaving Saudi Arabia, Topuzdag also trained Saudi engineers who later went on to manage audio systems in mosques across the Kingdom.

What started as a problem he noticed during an Umrah trip became a 10-year mission to improve the sound of the two holy mosques.

True. In 1997 Turkish audio engineer Ahmad Tekin Topuzdag noticed severe echo, feedback and poor clarity during Umrah at Masjid an-Nabawi. Management let him test one section; the fix was so clear they hired him full-time.

Over the next decade he rebuilt the systems at both holy mosques: new mics, cables, speakers, mixers and EQs; voice-mapped each Imam and muezzin; split the space into seven zones; cut reverb and feedback; and added mics for full prayer coverage. Frequency range jumped from roughly 500 Hz–6 kHz to 100 Hz–19 kHz. He also trained Saudi engineers who later ran mosque systems across the Kingdom.

Masha Allah maintaining Audio system and electricity with zero percent failure in haramain is a miracle.

Any one has used the services of this consultant.

Do they offer services to build a PA system for an existing multi floor mosque. These building are not planned for acoustics optimization. The consultant has to adopt the existing structure and offer best audio system. What is the budget.

I came across websites of "AUDIO SYSTEMS FOR CHURCHES". Here these forums offer advises to improve PA system for churches. Can brothers in UK create similar forum for Mosques.

Also brothers can pool funds and purchase expensive Audio simulation software with open licence and advise mosques around the globe.

Why specifically UK mosques?

There's a company called SALAH SOUNDS LTD, they offer these services.

A simple question.
what should be the spacing between ceiling speakers for a given height of a masjid. Power in watts for these speakers.

The simulation software can be used globally for mosques.

They are welcome to contact salah sounds at [email protected] or just contact a sound technician/ engineer in your locality.

Concert Hall:

An Imam is reciting Surah Yaseen

  • The recitation of the Surah Yaseen is SIGNAL
  • The shuffling of the Imam's clothes, the air conditioner blowing the air passing to the microphone is NOISE
  • In order to achieve as much purity as possible you want highest SIGNAL captured and lowest NOISE captured
  • The walls are specifically coated with material to dampen NOISE, you usually see cones
  • Chairs are also designed to dampen NOISE, the material is spikey
  • The Microphone is specific and directional and since Imam is not moving the MIC is better able to cope with SIGNAL


Now, imagine the someone in the front row sneezes, that is an accident which spikes the NOISE but the coating and material on the walls is specifically designed to break up sound waves before reflecting it back so NOISE of the sneeze is dampened

Masjid:

An Imam is leading Salah in a Masjid and reciting Surah Yaseen

  • The recitation of the Surah Yaseen is SIGNAL
  • The shuffling of the Imam's clothes, the air conditioner blowing the air passing to the microphone is NOISE
  • In order to achieve as much purity as possible you want highest SIGNAL captured and lowest NOISE captured
  • The Microphone is specific and unidirectional but the Imam is moving so the it is not always directionally aligned
  • In Haram you have a mix of solid vs hollow vs open spaces and sound waves must compliment instead of cancelling each other.


Now, imagine the Maudhin sneezes, that is an accident which spikes the NOISE and the system must be able to dampen the accidental NOISE of the sneeze, there are no absorbent materials to break the sound wave and it must be transmitted live

That's why sound system in a Mosque is so difficult to capture and transmit and the entire effort is to keep highest SIGNAL captured and lowest NOISE captured

This is what a sound Engineer is aiming to do:



This is what an amplifier does, tries to boost the SIGNAL to NOISE ratio


Haram is a combination of solid, hollow and open structures so sound must not overlap, contradict. In a hall its must easier because the audience is in a single place so you can direct sound at a specific location but in Haram people are standing all over the place...

Its not about power of speakers! Its about placement, people, what's happening in the Masjid, air density etc and that's why sound systems need adjustments from time to time.

If you want to do it yourself then start with an empty Masjid and have someone recite the Qur'aan and move speakers around and temporarily place them and listen and move them around.

Then conduct your testing in a Bayan full of people and sometimes full and sometimes empty and test.

Learn your amplifier settings during Bayan.

Qur'aan and Bayan are different sounds so repeat tests and have others listen.

Once ready then fix the speakers into walls/ceiling, after that the only adjustment is through your amplifiers as sound wave pattern is now affixed.

You get what you are willing to pay for, I suppose many Muslims DIY sound engineering but overtime you learn a lot, I did this for my Mosque and over a long time we learned how to minimize NOISE

I saw this in one masjid. Very useful and effective in feedback/echo suppression. The existing building can be adopted with this device. Expensive, 20,000 rupees but useful for masjids who can afford.

[ATTACHMENT4199]

Behringer FBQ100 Shark Automatic Destroyer with Integrated Microphone Preamp, Delay Line, Noise Gate and Compressor

  • High performance single channel Feedback Destroyer with integrated microphone preamp, delay line, noise gate and compressor
  • Automatically and "intelligently" locates and destroys up to 8 feedback frequencies
  • Narrow FBQ filters for extremely effective feedback suppression, while keeping highest sonic quality
  • Ultra-low noise Mic/Line input with Gain control and +48 V phantom power
  • Delay line with up to 2.5 seconds of delay, adjustable in meters, feet and msec


note: video on Behringer FBQ100 is available on youtube, but youtube video needs halalification. there are female artists in video.

We can read the manual here:

This is a single channel system which means it only works with a single MIC at a time.

Secondly, you need a directional MIC for the Imam and the best system is a headset because the Imam moves up and down and you want the MIC to stay with him.

Thirdly, in India there are thousands of sound engineers who will configure the system cheaply, you don't need a Muslim for this...In fact, its probably easier to find someone in India then England

One of my previous Masjid had the sound system configured by a Sikh guy...

Even the acoustics experts fail when crowd numbers change or building expansions/alteration.
