Features
Read full description

In this simulation of a spring pendulum a mass is attached to two springs. You can touch the mass and move it out of its stable position. Or you can tilt your iOS device and watch gravity work. At all times you can alter the damping (k), the flexibility of the spring (D) and the mass of the steel ball (m). Take some time and play around with these parameters to become an expert in harmonic and not so harmonic oscillations. If you have found an interesting one, tap the graph button to record the displacement over the time. Tap the info button to enable or disable gravity and to export graphs into your photo library. Have fun learning physics! Use the app completely on your own risk and for educational purposes only. The simulation is an approximation. It might be wrong and different from reality.

Acoustics engineering Acoustical engineering (also known as acoustic engineering) is the branch of engineering dealing with sound and vibration. It includes the application of acoustics, the science of sound and vibration, in technology. Acoustical engineers are typically concerned with the design, analysis and control of sound. The branch of engineering that analyzes sounds and vibration in technology. It's the scientific application of implementing and developing solutions to reduce unwanted noise and vibrations caused by machines and human activity. Noise abatement technologies can reduce noise pollution in settings such as airports, schools, factories, office buildings, homes, bridges and train stations. Acoustic engineering may also enhance the acoustical experience in concert halls and recording studios. Audio Engineering Audio engineering is a broad field, and there’s a lot more to it than you might think. With a wide range of career options and responsibilities, audio experts can perform a myriad of jobs. Here is your ultimate guide to what audio engineering is, so you can understand the ins and outs of the audio world. Audio Engineer Roles There are five specialized roles within the world of audio engineering: recording engineer, mixing engineer, mastering engineer, live sound engineer, and multimedia sound engineer. Each plays a specific role within the music industry, and the path to each career has its own unique characteristics. What Does an Acoustic Engineer Do? Acoustics engineers are electronics engineers who specialize in designing and developing technologies that solve problems related to sound. For instance, they may apply fundamental scientific principles to find ways to monitor and manipulate sound levels or improve sound clarity. Depending on their area of interest within the field, acoustic engineers may specialize in architectural acoustics, noise control, structural acoustics or underwater acoustics. They often work with architects on building designs, but they can also find jobs related to noise reduction in factories and other industrial environments.
