Welcome Center showing the Pulse Settings file for Introduction to LabChart 8 The LabChart Interface LabChart has a predictable interface focused around the main LabChart window, the menu bar and toolbar at the top, and the document buttons at the bottom. The various windows for data files exist within this main window.

Find your sound's intensity in watts/square meter. For everyday practical purposes, decibels are usually seen as a simple measure of loudness. However, the truth is a little more complex. In physics, decibels are often thought of as a convenient way of expressing the intensity

• In this geology science project, you will use global seismometer data from earthquakes to measure the actual angle between earthquakes and their seismic shadows, and use the angle you find to calculate the diameter of the Earth's core.
• While we were at it, AdInstruments also released fresh versions of LabChart Reader (8.1.9) for Mac and Windows, and Spike Histogram (v2.6.2) for Windows. The Spike Histogram update allows you to copy and paste both images and text using the 'Copy Spike Discriminator View' menu item.

of a sound wave. The larger the amplitude of a given sound wave, the more energy it transmits, the more it moves the air particles in its path, and the more 'intense' the sound is.^[5] Because of this direct relationship between a sound wave intensity and its volume in decibels, it's possible to find a decibel value given nothing more than an intensity level for the sound (which is typically measured in watts/square meter)

• Note that, for ordinary sounds, the intensity value is usually very small. For instance, a sound with an intensity of 5 ×10^-5 (or 0.00005) watts/square meter translates to about 80 decibels — about the volume of a blender or food processor.
• To better understand the relationship between intensity measurements and decibels, let's follow along with an example problem. For the purposes of this problem, let's say that we're music producers and we're trying to find the background noise level in our recording studio to improve the sound of our records. After setting up our equipment, we detect a background noise intensity of 1 × 10^-11 (0.00000000001) watts/square meter . In the next few steps, we'll use this info to find the decibel level of the background noise in our studio.
