Washer Noise Level Measurement: How It Works and Ways to Reduce Vibration

Introduction: Why is Washer Noise Level Important?

A washing machine is an essential appliance for a modern home. But when this device runs, its noise and vibration can be disturbing for many. Especially in city apartments where multiple families share the same wall, the loud noise of the washer can sometimes cause discomfort.

Also, many people make their purchase decision based on the noise level of the washer. Because most of the time the washer is placed near the bedroom or living room, where the impact of noise is felt more. So it is important to have a proper idea about the noise level of the washer before buying it.

Noise Level Measurement: How is it done?

There are several standard methods used to measure washer noise levels. These methods are internationally recognized and approved by quality control bodies of various countries. Let’s look at the basics of noise level measurement:

1. Use of the Decibel (dB) scale

The decibel (dB) scale is most commonly used to measure noise level. Decibel is the unit of measurement for noise intensity. This scale is designed to match human hearing. Usually:

• 30-40 dB: Very low noise, almost silent.
• 40-50 dB: Sound similar to normal conversation.
• 50-60 dB: Quite loud, which can be annoying.
• 60-70 dB: Loud noise, which is hard to tolerate for a long time.
• 70+ dB: Very loud sound, which can damage hearing.

Noise level of a washer is usually between 45-75 dB. However, in high-quality washers, this noise level is below 50 dB, which is quite tolerable.

2. Equipment used for Noise Measurement

Special instruments are used to measure noise level, such as:

• Sound Level Meter (SLM): It directly measures the intensity of noise and expresses it in dB.
• Microphone and Data Logger: Used to monitor noise frequency and changes over time.
• Acoustic Chamber: A special chamber where the reflection of noise is reduced and accurate measurements are ensured.

4. Standard Methods for Noise Measurement

Several international standard methods are used to measure washer noise levels. Some notable ones include:

• ISO 60704: Used to measure the noise level of washers and dryers.
• IEC 60704-2-4: Specially designed for measuring the noise level of washing machines.
• ASTM E1275: US standard for noise level measurement.

Noise measurements made following these standards are reliable and comparable.

4. Factors Considered During Noise Measurement

Some important points to keep in mind while measuring noise level:

• Washer Location: Noise measurement takes into account where the washer is placed. Noise measurement is usually done in free space so that the effect of reflection is less.
• Washer Speed Setting: The speed at which the washer is running affects the noise level. Noise is usually higher at higher speeds.
• Washing Mode: Noise level may vary in different washing modes. For example, noise is higher in heavy wash mode.
• Environment Around the Washer: Noise level of the surrounding environment is also considered while doing noise measurement.

How To Reduce Vibration: Tips To Keep Your Washer Quiet
