What Means, New SMPTE Pink Noise…and How?

SMPTE ST-2095-1 is a new standard for Pink Noise. It took a great deal of work by a great number of clever people, a lot of listening and testing and tweaking. The cool thing is that it isn’t made with a lot of transiticators, but rather, with digits. This is THE Digital Pink Noise Standard.

Pink Noise has been one of those things that has always been around, and people don’t think much about it. Flick a switch, and there it is. But it took a sophisticated circuit to do right, and it wasn’t always implemented the same…or even well. That is much less likely now because with the standard is a python script that is very easy to implement. Continue reading “What Means, New SMPTE Pink Noise…and How?”

Do This First…An Evolving Story – Sound

Since there are many goals and purposes for this project, there are many things that need to be done.
Fortunately, they don’t all have to be done at the same time.

So, if you don’t have the organizational support to download DCPs onto a USB drive and load them into the Media Player/Projector system, you can still download some audio and light measuring tools, and experiment with them until you can use them easily in a dark room.  Continue reading “Do This First…An Evolving Story – Sound”

Audio (Basics): Part 2

Hi again.

At the very end of Audio (Basics), Part 1 we introduced the concept of Frequency when discussing waves. We also mentioned some basic information about the speakers in the room, which create the waves that we eventually hear. This article will build from there. You can skip all of this and you can still talk to a technician, but it is really simple. It just looks long because there are a lot of examples. Continue reading “Audio (Basics): Part 2”

So Now You Want To Measure Sound Level

Hopefully you have read through the post named Basics: Audio (Sound), Part 1 and Part 2. It is good to have a basic understanding of frequencies and speakers and surround and amplifiers and level and Loudness. Hopefully you’ve noticed some of the many ways that the human hearing system has made things “interesting” in normal life, and while you have walked around your cinema theaters since learning more about these things.

Basics: Audio (Sound)

Sound is all around us. We don’t need any particular talent to use it. Doctors tell us that we can hear sounds in the womb.

Using sound well is a different story. Being able to judge sound so it is the best possible for your clients is another different story.

For a simple definition, “Sound” is what we hear. But actually every sound involves hundreds of steps. These steps start with a motion that occurs at one point. You can think about it like a pebble that is thrown into a pond.
