About This Chapter
Acoustics in Engineering - Chapter Summary
Acoustics are very important to the ambient atmosphere of a building. Use the lessons in this chapter to learn how engineers measure and account for sound in a structure. You can also learn the formulas they use to estimate the sound pressure level of a building. Review this material whenever you find the time, without fear of losing your place. The Dashboard in your account makes it easy to jump between different devices, and, when you have finished the lesson material, you can quickly assess what you learned with the interactive lesson quizzes. Use this chapter to explore:
- How engineers measure decibels
- What sound pressure level (SPL) is
- The formulas used to estimate and account for the sound pressure level of a building
- Why sound management is important when designing a structure
1. How to Measure Decibels: Instruments & Scale
Did you know there is a way to measure exactly how loud a sound is? In this lesson, learn all about the decibel scale and about some of the instruments used to measure sound level in decibels.
2. Sound Pressure Level Measurement & Formula
We use our ears to hear. Sometimes we can't hear a noise that is there, and sometimes the sound is so loud it hurts. This lesson will explain sound pressure levels and how they are calculated.
3. What is SPL (Sound Pressure Level)? - Definition & Examples
The pressure within a sound wave determines the loudness of the sound. In this lesson, learn how to calculate the sound pressure level of a sound wave and what this measurement represents.
