PA Design – Sound Studies – Part 1

When your voice is understood

Part 1 – Evaluation / Budget Planning

Do you remember past times?

In the past, say 30 years ago, a PA system was usually designed by experienced engineers and technicians, with more or less – good results.

There was no possibility to predict the dispersion of a speaker structure in an industrial area with their machines and installations and to calculate the effective signal-to-noise ratio due to poor computing power.

Therefore, some rules of thumb were developed to meet common and simple requirements.

And if there was no rule of thumb for your existing project?

…then the simple ‘The More the Better’ motto was applied…

And now?Checklist_PA

We at INDUSTRONIC work in a different manner. The PA design is strictly made and calculated with different software applications and hardware appliances. However for our design work we need more data from our customers than before.


To facilitate your work we prepared some checklists which retrieve the following data:

• Type of speaker/s
• Hazardous areas
• Ambient noise/s
• Plot plans of areas
• Buildings / Side views
• …

When we get this data back, our engineers can then calculate and create a bill of material (BoM) of the equipment required.


Ambient noise?

In some cases, while there is no ambient noise map available, there is a need to measure and map the ambient noise. This can be done by third party companies selected by the customer or by INDUSTRONIC.

For budget planning it should be sufficient to calculate only with a few ‘large surface noise carpets’ to build the noise map and obtain the amount of devices (speakers, flash beacons if noise > 85 dB).

The calculation program works with the simple ‘1/r inverse distance law’. Some parameters like speaker type, general absorption, general ambient noise, signal to noise and power tapping must be inserted additionally.


See the Results!

As a result we get the ‘undisturbed range’ of the speaker with the
parameters entered.

With this range we can calculate the total amount of speakers.

What about indoor areas?

In indoor areas like admin buildings, workplaces and living quarters there should be at least 1 (one) loudspeaker in each room with doors.


On the one hand it is due to regulations or standards, on the other hand it is logical that everybody should be alarmed in case of fire…


That’s all?

Not yet – some documents must be created where all speakers are correctly assigned to the places required.

For more precise sound planning some of our customers need a so-called sound study. But this is another story – learn more in our Part 2 of PA Design / Sound Studies.

Quality Management System Successfully Recertified

DIN ISO 9001_2008 quality management system certificate_engl

Our new DIN ISO 9001:2008 Certificate is valid until April 2018

Once again, INDUSTRONIC has been recertified with the DIN ISO 9001:2008 certificate.

Every 3 years, a recertification audit takes place to renew the certificate for our quality management system. The audit is executed by an independent third party accreditation body (in our case DEKRA). In March, two external auditors visited the company to make sure that all our processes comply with the regulations of the DIN ISO 9001:2008 standard.

During their visit they questioned the managers and employees of several important processes. Beside others, the following teams were checked:

  • Product development
  • Production
  • Purchasing
  • Sales & Project Management
  • Project Engineering
  • Marketing

After thorough examination, our processes were found to be working fine. Further elements of the quality management system are the determination of customer satisfaction and the assessment of the management. We have fulfilled all necessary requirements and therefore, the audit was passed successfully.

The new certificate is now valid until April 2018. In the following two years, one surveillance audit per year is obligatory according to the DEKRA regulations.

On Saturday the 21st March, we celebrated our corporate anniversary with a great gala event. All employees were invited together with their partners. Even the CEOs of our subsidiaries from Bejing, the USA and Singapore joined us. Moreover, some friends of the company and representatives of the local politics, press and the Chamber of Industry and Commerce (IHK) came to the nicely decorated festival hall.

The highlights of the evening were the amazing tricks of the two magicians Joe Walthera & Pafema who let a table fly above the stage and made white pigeons appear out of nowhere.


When comedian Schorsch Bross showed his abilities on juggling rings high upon a unicycle, the audience enthusiastically applauded. Together with a female singer, the local band “Würzbuam” ensured a good atmosphere.



IHK-Certificate of Honour for 50 years

President and shareholder Wolfgang Stallmeyer welcomed the guests and gave a brief look back on the history of the company.

Then, greetings were delivered by the Mayor of Wertheim, Mr. Wolfgang Stein and by one of the original founders of INDUSTRONIC, Mr. Siegfried Köster. Professor Dr. Dieter Salch, whose role is head of the advisory board and company attorney, spoke about the beginnings and growth of INDUSTRONIC.

After that Mr. Christoph Geiger from the Chamber of Industry and Commerce Heilbronn-Franken handed over a certificate of honour for the 50th company anniversary to Wolfgang Stallmeyer.


After the speeches, the official part ended and Wolfgang Stallmeyer opened the buffet. The delightful international buffet offered specialties of four continents and was highly frequented. However, it was almost impossible to try all the different warm and cold dishes. Later, the guests could choose from a variety of cocktails and drinks at the bar. Others were just chatting or showed their dancing skills on the dance floor.

All employees and guests had an entertaining evening and will surely remember this successful gala event for a long time.

Today´s topic of INDUSTRONIC functions is the “Conference” where several members are connected with each other via a conference channel.

All Subscribers Can Speak to Each Other

You use conferences if you want to easily and quickly connect several subscribers from different locations. They can then talk about operational processes or discuss the next work steps, for example. Conferences are held in half-duplex mode. This means that the members can speak and listen alternately, but not simultaneously.

Step 1: Initiate a Conference

First, you trigger a group call or an all call to invite members to a conference. The members required are asked to log into the mentioned conference channel.

Step 2: Log In

To log into the conference each member presses the respective conference channel key at his station. Each member can now listen to all conversations held in this conference.

Step 3: Speak Into the Conference

To speak into the conference, a member presses the respective key at his station which is exclusively reserved for this purpose. He then keeps it pressed and speaks into the microphone (Push-to-Talk).

Communication Procedure

The following illustration shows the conference procedure in detail.




















































You can assign an individual priority for each conference. This means that an active conference overrides functions with the same or lower priority. A conference can only be interrupted by a voice connection or function with a higher priority.

Conference Master

For each conference you can optionally assign a master intercom station. Only this conference master can then initiate the conference and invite members. When the conference master logs out again, the conference is terminated and all other members are also logged out.

INDUSTRONIC Travels the World

Ever since INDUSTRONIC has maintained close relationships with customers and sales partners worldwide.

We prefer to have direct contact to all parties involved in a project in order to:

  • Discuss questions which may arise or analyze and evaluate project requirements,
  • Inform about new products or services, and
  • To enter into a dialog with the people on site to become familiar with local processes and project requirements.

We strongly believe that the best result can be achieved by having early face-to-face contact with our customers and partners and collaborate right at the beginning of a project.

Furthermore, we want to constantly optimize our products and consulting services to adapt them to the specific needs of the different markets.

This year, our Area Sales Manager responsible for the Middle East started with a seven-day business trip to the United Arab Emirates. Interested parties could participate in more than 15 technical workshops. Many thanks to our highly esteemed sales partner Hatta Trading & Services Est. who supported us and successfully organized the events.

In February again, we visited our customers in India for nearly two weeks.INDUSTRONIC in India

Our President Wolfgang Stallmeyer and the responsible Area Sales Manager held hotel workshops in important (industrial) cities such as Mumbai, Vadodara, Kochi, and Bangalore.

Above all, the aim of this journey was to make new contacts. Furthermore, they used this occasion to meet with various customers and to discuss current projects.

Our long-standing sales partners Dee-Em Systems (Mr. Mukesh Shah) and Indcom Engineers (Mr. Ashok Bhat) accompanied and supported them actively.

For more than 20 years now, we can count on their dedication which enables us to constantly expand our local networks and to establish long-term relationships with our customers.

We would like to take this opportunity to say a big thank you to all of our sales partners worldwide for their hard work and exceptional commitment. With their competence and outstanding customer orientation we are able to support our customers on this scale and to provide them with reliable and high quality products.

President Wolfgang Stallmeyer and members of the “Oktavenspringer”.

Thank you once more for supporting our ongoing Christmas Charity Campaign “Donations Instead of Gifts”.

Worldwide you, our customers and partners, cast your online votes for one of four charity organizations. From this selection the donation amount of € 6,000 will be distributed according to the votes cast.

Again, the “SOS Children’s Villages“ received most of the votes and will use the fund for a newly opened family center in Frankfurt. The “Worldwide Initiative for Social Commitment” came in second supporting the “Las Hormiguitas” Center for Social Promotion in Nicaragua.

In third place, the DAHW – German Leprosy and TB Relief Association will be supporting the fight against Ebola. Fourth place goes to the local project – the choral society “Oktavenspringer”.

INDUSTRONIC is happy to see that the donations will now be put into action and is proud to support the valuable work of these charity organizations!

Page & CallBack

In my latest blog posts about INDUSTRONIC functions I introduced you to different one-way and two-way communication procedures. Today´s function combines these two types of voice connections in one application – the so-called “Page & CallBack” function.

You use Page & CallBack if you want to address a person who is somewhere in the plant, but you don´t know exactly where. After the person concerned has called back, both subscribers can speak to each other.

Paging All Individuals

First, you establish an all call and page the specific person. In the announcement the person concerned is asked to call back by dialing a specific call number.

 Private Two-way Communication

The person concerned goes to the next available intercom station and as soon as he calls back, an exclusive two-way connection is established. Both subscribers can now speak and listen alternately, but not simultaneously. All other subscribers cannot listen.

Communication Procedure

The following illustration shows the Page & CallBack procedure in detail.





Duplex Mode

As soon as the person concerned calls back, the conversation can also be held in full-duplex mode. Both subscribers can then speak and listen simultaneously. By default, the conversation is held in half-duplex mode as two-way connection.


For the announcement (Page) at the beginning of the communication procedure you can assign different priorities to the intercom stations used. Usually a control room intercom station has a higher priority than an outdoor intercom station. This means that the control room can interrupt an active all call established by an outdoor intercom station and trigger its own call.

Pre-tones and Warning Beacons

It is possible to play back a pre-announcement tone prior to the call. A positive effect is that listeners stop their conversations or noisy activities to focus on the announcement that follows. Furthermore, there is the option to activate flashing warning beacons which indicate the call visually.
