<h2>Do you have a noise problem?</h2>
<p>
  Your windows and doors are the weakest part of your property. In fact, over
  95% of windows and doors installed in Malaysia today, offer little protection
  from noisy roads, construction or airplaines. Even worse, they do not offer
  sufficient protection from burgularly and are often found to be leaking.

<h3>What can noise do?</h3>
<p>
  <b>Noise stress is a major cause of illness</b>. It not only damages one’s
  hearing, it also leaves persistent marks on the human psyche. For many years,
  effective protection against undesired noise has not merely been a matter of
  comfort, but a decisive issue in health protection. If you want to learn more,
  check out the
  <a href="/assets/files/Q-Windows-Soundproofing-Brochure.pdf"
    >German Windows Noise Brochure <small>(PDF, 4.1 MB)</small></a
  >.
</p>

<h2>Reduce perceived noise by up to 99%</h2>
<p>
  A proper sound insulation can only be achieved when all components play well
  together. The final sound insulation factor depends on the weakest element.
  Therefore it’s important to take all factors such as glass, profile and
  installation into consideration.

<div class="grey-backgdrop">
  <p>
    <span
      class="glyphicon glyphicon-chevron-up green"

    If the sound level (volume) <strong>drops by 10 dB</strong>, it is perceived
    as <strong>half as loud</strong>.
  </p>
  <p>
    <span
      class="glyphicon glyphicon-chevron-down red"

    Conversely, if the sound level <strong>increases by 10 dB</strong>, it is
    perceived as <strong>twice as loud</strong>.

<h2>Determine healthy sound level</h2>

<div class="row">
  <div class="col-sm-6">
    <h3>Recommended sound level</h3>

    <p>
      Bedroom 30 - 35 dB <br />Study room 35 - 40 dB <br />Living room 40 - 45
      dB <br />Home office 45 - 50 dB
    </p>

    <p>
      By subtracting the recommended indoor noise level from the typical outdoor
      noise level, you can estimate the appropriate acoustic performance for
      your windows.
    </p>

    <h4>Example calculation</h4>

    <p>
      1. External noise source: 76 dB (road traffic) <br />2. Desired room noise
      level: 35 dB (bedroom) <br />= The difference is 41 dB
    </p>

    <p>
      In this case, a 41 dB rating is required for your German Windows window
      and door system.

<h3>Terms and definitions</h3>

<p><strong>Rw [dB]</strong> is the weighted sound reduction index</p>
<p>
  <strong>Rw + C [dB]</strong> rating includes an adaptation for mid to higher
  frequency noise sources such as speech, so called “pink noise”, integrated
  into a single number as outlined in EN ISO 717-1.
</p>
<p>
  <strong>Rw + Ctr [dB]</strong> rating includes an adaptation which considers
  lower frequencies noise sources such as aircraft (on land), trains and
  automobiles and integrated into a single number as outlined in EN ISO 717-1.
</p>
<p>
  <strong>STC [Sound Transmission Class]</strong> The STC rating was created to
  provide a single number rating for interior building partitions that are
  subjected to interior noises such as speech, electronic devices, office
  equipment and other mid to high frequency noise sources. STC ratings are
  calculated in accordance with ASTM E413 over the frequency range of 125 to
  4000 hertz.
</p>
<p>
  <strong
    ><strong class="blue">OITC</strong> [Outdoor-Indoor Transmission
    Class]</strong
  >
  The OITC rating was created to provide a single number rating for facades and
  facade elements in relation to exterior noise from aircraft, trains,
  automobiles, and other low to mid frequency noise sources. OITC ratings are
  calculated in accordance with ASTM E1332 over the frequency range of 80 to
  4000 hertz.
