Plastic whistles are used in a variety of contexts, from sports to emergency situations. The decibel level of a whistle is important in determining its effectiveness and potential impact on human hearing. Decibels (dB) are units used to measure the intensity or loudness of sound. A typical sports whistle can produce a sound of around 100 dB, while referee whistles typically range between 102 and 120 dB. The Storm whistle, used in safety and rescue operations, is one of the loudest whistles, measuring between 118 and 120 dB. Plastic whistles, first manufactured in Britain in 1914, offer design variations and colours, and are generally lighter and more versatile than metal whistles.

What You'll Learn
Plastic whistles vary in decibel output
Traditional referee whistles, commonly used in sports, typically produce sounds ranging from 102 dB to 120 dB. The intensity of these whistles depends on factors such as the force and technique used when blowing them, as well as the specific brand and model. For example, the Fox40 Mini, a referee whistle, produces a sound of 109 dB, while its older version, the Fox40 Classic, emits a louder sound of 115 dB.
The design, size, and materials used in whistles also contribute to their decibel output. Plastic whistles, for instance, were first manufactured in Britain in 1914, and their popularity grew due to the design variations and colours they offered. Plastic whistles are known to be lighter in weight and provide a cushioned mouth grip with a comfortable temperature. They are also versatile, as they can be used underwater, like the Windstorm and HyperWhistle models.
Some plastic whistles are designed to be compact and sleek, like the Windstorm, which is a more compact version of the Storm whistle, the loudest whistle in the world. The Storm whistle has a decibel range of 118 dB to 120 dB, and its unique design allows it to be heard through walls, glass, and water.
While plastic whistles vary in decibel output, it is important to remember that prolonged exposure to sounds above 85 dB can lead to hearing loss. Therefore, it is essential to use whistles responsibly and be mindful of the potential risks associated with their high-intensity sound.

Plastic whistles are used in safety devices
Plastic whistles are used in a variety of safety devices and situations. They are a deceptively simple invention that can be used in a wide range of scenarios. For example, whistles are used by train conductors, referees and coaches, and for safety and survival in the outdoors. Whistles are often favoured over the human voice as they carry further and are more effective in loud conditions and over long distances.
Plastic whistles are also used in boating and sailing. They are a required piece of safety equipment on every boat by the U.S. Coast Guard, and it is recommended that each life jacket should have a whistle attached to enable audible signalling if a person falls overboard. Boaters and rescue teams use plastic whistles because they are waterproof and powerful. The Storm Whistle, for example, was invented to work underwater and can be heard through walls, glass, and water. It is used by Navy Rescue boats, boaters, and search and rescue teams worldwide.
Plastic whistles are also used in diving. The Storm Whistle, for example, is used by dive clubs to organize multi-diver events and to signal to fellow divers underwater.
In terms of decibels, the Storm Whistle measures between 118 and 120 dB, while the Fox 40 Mini is 109 dB and the Fox 40 Classic is 115 dB.

Plastic whistle design variations
Plastic whistles were first manufactured in Britain in 1914, and their design has been subject to variations in shape, form, and colour. Inventors continue to develop new types of whistles, with the introduction of plastic whistles that mimic the sound of traditional referee-style whistles.
Plastic whistles can be designed to be pea whistles or pealess. Pea whistles contain a small ball, known as the "pea", made of plastic, hard rubber, or cork. The cork pea is synthetic and moisture-repellent, preventing it from getting stuck inside the whistle. The pea moves chaotically in the chamber, interrupting and modulating airflow to create a warbling or shrieking effect. The Fox40 Pearl, Acme Cyclone 888, and Molten Dolphin are examples of plastic pea whistles. On the other hand, pealess whistles like the Fox40 Mini and Fox40 Classic do not contain a pea, producing a flat tone.
Plastic whistles can also vary in their ability to be used underwater. Dr. Howard Wright invented the Storm Whistle in 1988, which is the most powerful whistle in the world and can be heard through walls, glass, and water. It is used by safety and rescue teams worldwide. The Storm whistle is waterproof and easy to hold and hear. The Windstorm whistle is a more compact and sleek version of the Storm, with a slightly lower decibel rating.
The pitch of a plastic whistle can be altered by changing the chamber or the opening of the chamber. The frequency of the sound is dependent on the length of the whistle, with longer whistles producing lower pitches. Plastic whistles can also vary in their shape, ranging from straight tubular designs to torus shapes like the apito de samba, which magnifies the sound-making potential.

Plastic whistle durability
Plastic whistles are known for their durability and are a popular choice for outdoor activities. They are made from tough, shatterproof plastic and can withstand being dropped and knocked. While no whistle is truly indestructible, a plastic whistle can be expected to last for years. They are also more comfortable to use in cold weather. ABS plastic whistles, in particular, offer greater pitch stability in varying temperature conditions compared to metal whistles. This makes them ideal for use in diverse environments or frequent temperature fluctuations. Additionally, ABS plastic whistles are highly durable and resistant to moisture, making them well-suited for outdoor use or humid conditions. Brands like Susato Whistles utilise ABS plastic in their designs, and their whistles are known for their loud volume and bright tone.
When choosing a plastic whistle, it's important to consider factors such as durability, tonal qualities, and cost. Plastic whistles offer a cost-effective option without compromising on quality. They are also lightweight, making them a preferred choice for ultralight backpackers or those looking for a comfortable option for extended use. The mouthpiece material of a plastic whistle can impact its sound and appearance, offering a unique playing experience.
The durability of plastic whistles also extends to their use in safety and survival situations. Safety whistles made of plastic are widely used and trusted by rescue teams and boaters due to their waterproof capabilities and powerful sound. For example, the Storm whistle, invented by Dr. Howard Wright, is the loudest whistle in the world and can be heard through walls, glass, and water. It has a decibel range of 118 to 120 dB, which is significantly louder than a motorcycle at 100 dB or a loud rock concert at 115 dB. The Storm whistle is used by Navy Rescue boats, boaters, and search and rescue teams worldwide because of its waterproof design and powerful sound.
While plastic whistles offer excellent durability, it's important to note that their sound can vary. Some plastic whistles, like the Fox40 Mini, produce a sharp tone that is loud enough for its intended purpose without being excessively loud, registering at 109 dB. In comparison, its counterpart, the Fox40 Classic, produces a louder sound at 115 dB. Ultimately, the durability and sound quality of a plastic whistle make it a versatile and reliable choice for a range of activities, from outdoor recreation to safety and survival situations.

Plastic whistle sound augmentation
Plastic whistles can vary in the decibels of sound they produce, with some emitting up to 118 dB or more. The frequency of sound produced by a whistle is dependent on its length, with longer whistles producing lower-pitched sounds. The material used also affects the sound, with metal whistles generally producing louder blasts than plastic ones. Plastic whistles with a "'pea'" or ball inside can create a louder sound with less air pressure as the ball affects the airflow.
The sound of a whistle can be augmented by altering the shape and size of its openings. Changing the chamber or opening of the chamber will modify the sound, though the specific outcome is unpredictable. The Storm Whistle, invented by Dr. Howard Wright, demonstrates how the principles of sound augmentation and amplification can be applied to whistles. Dr. Wright discovered that the sound-producing area of a whistle is a small 5mm x 5mm area over the whistle exit opening. This knowledge allowed him to create a prototype that functions while submerged underwater, as the whistle's sound-producing area could still be exposed to air.
The Storm Whistle is used by dive clubs, Navy Rescue boats, boaters, and search and rescue teams worldwide due to its loudness and waterproof capabilities. It has a decibel rating of 118-120 dB, making it nearly twice as loud as its competitors. The Windstorm whistle is a more compact and sleek version of the Storm whistle with a slightly lower decibel rating. Both whistles are packaged with a lanyard, allowing them to be worn around the neck or wrist, or attached to a backpack.
Plastic whistles designed for sports and safety applications are commonly available online and through retailers. These whistles often feature thickened plastic for durability and may include a "pea" or ball to enhance the sound. They are marketed towards coaches, referees, teachers, and emergency or survival situations where a loud, attention-grabbing sound is required. Some users describe the sound as "ear-shattering" and capable of quieting talkative middle school students.
