Background Information
Sewing machines have come a long way from the foot pedal operated contraptions first invented in the 19th century. Mechanical and electronic machines have been produced for almost two centuries and are a recognised part of many people’s everyday life. The range of machines and their functions vary, as do the levels of noise they produce. Recent technological advances have made sewing machines much quieter than older models, resulting in increased sales of many varieties.
Relevant Data
Studies have shown that an average mechanical sewing machine creates decibel levels ranging between 65 and 90 DB when used. DB stands for decibels and is a measure of loudness of a sound. Experiments conducted by the University of California suggest that the minimal noise level produced by a mechanical machine is 66 DB, while the noise level produced by electronic models can be as low as 50 DB.
In comparison, a washing machine has a noise level of about 70 Db and a dishwasher about 55 Db. Environmental Protection Agency in the United States estimates that the level of constant sound from a normal conversation is around 40 Db.
Expert Perspective
Noise emitted by mechanical sewing machines can vary significantly depending on their model and design, but generally speaking they are nowhere near as loud as people might expect. Experts suggest that there are a few basic steps that a user can do to reduce noise production such as keeping the machine clean, lubricating all the moving parts, and ensuring that the machine is well maintained.
The type of material being sewn can also have an impact on the noise level produced, with finer materials creating a quieter sound than thicker materials.
Analysis and Own Insights
From a personal perspective, sewing machines can be quite loud and unpleasant to the ears, but often this is only when sewing on materials that are thicker or of a coarse texture. Many manufactured and high-end machines have the ability to change their speed, allowing the user to reduce the intensity and speed of the needle while still getting the task completed.
I have also found that machines can become quite loud if they are not well maintained, with any malfunctioning parts or a lack of lubrication all contributing to an increase in noise production.
Advice for Minimising Loudness
Sewing machines noises can be reduced if the following advice is kept in mind when operating a sewing machine:
– Always ensure that the machine is clean and properly oiled, as this will help to avoid unnecessary friction between the components and reduce noise.
– Change the speed of the machine according to the type of fabric and thread being used. Slower speeds will result in a quieter sound.
– Choose the right needle and presser foot, as these can help reduce noise and produce more consistent stitches.
Advancement in Technology
Recent technological advancements have made modern sewing machines much quieter than the ones used a few decades ago. Many electric sewing machines are now equipped with advanced features to reduce noise production further, including sound insulation and electronic tension control.
New features not only help to minimise noise level but also guarantee a better and smoother stitching experience. For example, some modern machines are now equipped with an automatic threading feature which helps ensure that sewing is done accurately and quickly.
Motor and Electric System
The motor and electricity system is the most vital component in a sewing machine and is also the source of most of the noise. Motors of modern machines are put in an additional sound-case or box which helps to reduce the noise generated by the motor.
The electrical system is also crucial part of the machine and helps to ensure the smooth functioning of the machine. Advancements in this component have also allowed for a smoother, quieter operation of many modern machines.
Use of Sound-deadening machines
Many factories and textile production companies now use sound-deadening machines which help to reduce the noise generated by the equipment. These machines provide a silent environment with minimal vibrations, helping to minimise the noise produced by the machinery.
This technology is also available in domestic sewing machines in the form of sturdy metal cabinets and the like, which helps to trap the noise made by the moving parts.
Safety
Prolonged exposure to loud noise can lead to hearing loss and other health complications, which is why it is important to use sound protection when operating any type of sewing machine.
It is also essential to wear safety apparel such as glasses and ear defenders when using a sewing machine, as this can help to minimise noise and protect the eyes and ears from any potential harm.
