residential structures can result in noise pollution in the residential areas. Since over exposure of noise pollution may produce stress or hypertension for the person‚ they decided to find ways to make their respective place more peaceful by making their residential structures reinforcements to absorb incoming sound waves. They do this to avoid certain risks concerning health. This was called “Soundproofing”. Soundproofing is the method of reducing sound pressure with respect to a specified sound source

Sound and acoustics It is common to think that acoustics is the study of music. Although acoustics does comprise the study of musical instruments‚ it also includes an extensive range of topics‚ including: SONAR systems‚ noise control‚ ultrasounds for medical imaging and other processes‚ electroacoustic communication‚ seismology‚ etc. [1] In general‚ acoustics is the study of mechanical waves including sound‚ vibration‚ infrasound and ultrasound. When talking about the acoustics‚ it is essential

to protect Japan‚ he was followed by daymio and samurai‚ military figures that were placed in charge of administering the country‚ followed by farmers and artisans.

Indoor & Outdoor Acoustic Sounds Indoor Acoustics The Principles of Sound and Acoustics Sound is the apparent vibration of air resulting from the vibration of a sound source (e.g. guitar sound board‚ hair dryer‚ etc). We can describe such regular vibration in terms of the sum of simpler vibrations (harmonics). In other words any periodic oscillation and hence resulting waveform can be described in terms of the sum of its harmonics. Each harmonic being a simple sine wave (often called a
