Introduction
Intrusive and undesirable noise is affecting many lives, especially those living in busy
streets, near airports, construction industries and any other regions prone to noise. The issue
of noise and how to handle it in new housing developments is getting too complicated, and it
is considered in the context of doors and windows. These dwellings require proper acoustic
solutions so as to maintain a peaceful and quiet internal environment (Allen & Iano, 2013).
Windows are thought to be the greatest conductors of less to high-intensity noises in
industrial, commercial or even residential buildings. Sound enters and leaves through
windows thereby generating problems for those living in the room as well as outside.
Therefore one must employ appropriate acoustic alternatives to soundproof windows in order
to prevent the unwanted noise moving in and out of your room (Bailey, 2016).
Available options for making a sound control window
1. Retrofitting or replacing the existing window with a real sound control window
One of the most effective and best methods for soundproof window is retrofitting or
replacing the existing window with a real sound control window with an acoustical rating.
These noise attenuating windows are available in different sizes and specifications though
they are expensive to install and purchase. At the time of upgrading an acoustic performance
of a window, one must consider two alternatives; either replacing the windows or conducting
window retrofitting which attaches to the inner section of the existing glazing. There are
numerous advantages of window retrofits.
External noise, from moving vehicles and industries, travel so fast through glass
windows therefore this issue is addressed by installing such sound proof windows. These
sound control windows are rated in two main classes depending on how well these windows
prevent the movement of sound. These classes are; Sound Transmission Class (STC) and
Outdoor Indoor transmission class (OITC). Surprisingly, STC is the commonly used type of

comparing the acoustic effectiveness of the building materials like doors, walls and windows.
This method was designed to offer a single number rating for inside building partitions which
are under brought to noises such as radio, speech, television and other low to high-frequency
noise sources (Banias et al., 2011).
Secondly, OITC rating is for low and mid-frequency noises and it is used to measure
how good windows, doors, and walls prevent external transportation noises such as
automobiles, trains, and plains. The method is most important in buildings situated in
metropolitan regions, high traffic regions, near airports or other subways. Both ratings
depend on the number for a greater sound control- the higher the number, the better the sound
restrain. Using sound control windows are vast and provide several benefits. Attenuating
noise provide a comfortable space for your guests when they come for visits, it also
minimizes audio distraction during moments when you need a peaceful environment for self-
study (Coelho & De Brito, 2012 ).
Benefits of sound control window systems
 More peaceful and quite- this kind of windows keep unwanted noise to the
minimum hence creating a peaceful and silent atmosphere. They reduce sound
transmissions (Ding & Xiao, 2014).
Advantages of window retrofits Cost- Primarily, window retrofits are less costly compared to replacing the whole
window, which involves removing the permits, glass, and scaffolding (Eastman,
2018).
 Labor-saving- Conducting window retrofits needs less labor which saves your money.
 Air gap acting as a barrier- Employing window retrofits as a sound control system for
a residential building work better than replacing the windows, in that there is an
insulating air gap created between the new interior sound control window and the
