What Types of Noise Do Calmer Ear Plugs Block Out?

Earplugs are a simple but effective way to protect your hearing and reduce noise exposure. With many types of earplugs on the market, it can be difficult to know which is best for your specific noise reduction needs. This article provides an overview of the common sounds and noise levels that different earplugs can block out. We’ll look at the noise reduction capabilities of Calmer earplugs in particular, to help you understand how well they work for blocking different noise frequencies and volumes in home, work, and recreational environments. The goal is to give you the key facts to make an informed decision when choosing earplugs for your unique noise protection requirements. By understanding the noise-blocking capabilities of products like Calmer earplugs, you can protect your hearing health from excessive and harmful noise exposure.

How Earplugs Work

Earplugs work by physically obstructing the ear canal to block sound waves from entering. Most earplugs are made of soft, compressible materials like foam, silicone, or wax. When inserted correctly, these materials expand to fill the ear canal snugly from the ear opening to the eardrum.

Sound waves are vibrations that travel through the air in waves. As the sound waves reach the ear, they normally pass through the ear canal and cause the eardrum to vibrate, transmitting sound to the inner ear. Earplugs act as a barrier that absorbs and dampens these sound vibrations before they can reach the eardrum.

The snug fit of the earplugs against the walls of the ear canal creates friction that inhibits the sound vibrations from passing further down the canal. The compressible materials also transform the sound waves into subtle heat as they compress and expand from the vibrations. This transformation into heat energy further reduces the intensity of the sound that reaches the eardrum.

Overall, earplugs significantly muffle sounds by obstructing the ear canal physically and dampening vibrations before they can reach the middle and inner ear mechanisms. This allows dangerous high-decibel sounds to be reduced to safer levels.

Types of Noise

Noise can be categorized into different types based on various factors like duration and pattern. Here are some of the main types of noise:

  • Continuous noise: Noise that is steady, non-stop, and doesn't change over time. Examples include noise from appliances like fans, AC units, etc. This type of noise has a constant sound level over time.
  • Intermittent noise: Noise that stops and starts at intervals over time. The sound level goes up and down. Examples include traffic noise, construction noise, barking dogs.
  • Impact noise: Sudden bursts of loud noise caused by impacts. Examples are slammed doors, objects being dropped, hammering. Impact noises are abrupt and have a rapid rise and fall in sound levels.
  • Impulsive noise: Similar to impact noise but more intense. Examples are explosions, gun shots. Impulsive noises have almost instantaneous sound level peaks.
  • Fluctuating noise: Noise that fluctuates in loudness and frequency over time in an uneven manner. Examples are noise from crowds, playground noise.

Identifying the type of noise is important because different kinds of noise have different effects on hearing, sleep, concentration etc. Some types like continuous noise tend to be more disrupting over time compared to intermittent noise.

Noise Levels

The loudness of sound is measured in decibels (dB). Decibels are measured on a logarithmic scale, meaning that an increase of 10 dB corresponds to a tenfold increase in sound intensity.

Different types of noise fall into different decibel ranges:

  • Soft sounds like rustling leaves are around 10-30 dB
  • Normal conversation is about 60 dB
  • City traffic noise ranges from 70-85 dB
  • Power tools and leaf blowers are typically 100-110 dB
  • Jet engines at takeoff can reach 120-140 dB

Prolonged exposure to sounds above 70 dB can damage hearing over time. Noise above 120 dB is extremely loud and can cause immediate harm. Examples of harmful noise levels:

  • 85 dB: The sound of heavy city traffic. Exposure to 85 dB for 8 hours per day can gradually cause hearing loss over time.
  • 90 dB: The noise level of a lawnmower. 90 dB for 1 hour per day is the maximum exposure recommended by hearing health organizations.
  • 100 dB: A very loud radio, food blender, or motorcycle. Even short-term exposure to sounds this loud can cause permanent hearing damage.
  • 110 dB: A rock concert, power tools, or a car horn. Sounds this loud are painfully intense. Even brief exposure (under 1 minute) can permanently damage hearing.
  • 120 dB: Jet engines at takeoff. This level of noise causes immediate harm and pain.

Harmful Noise Levels

Prolonged exposure to noise levels above 85 decibels can cause gradual hearing loss over time. Here are some examples of noises that exceed this safety threshold:

  • Lawnmowers and leaf blowers (90-100 dB)
  • Power tools and shop machinery (100+ dB)
  • Motorcycles and small airplanes (90-115 dB )
  • Crowded bars, nightclubs and rock concerts (105-110+ dB)

The Occupational Safety and Health Administration (OSHA) requires safe noise exposure limits in the workplace. Workers exposed to 85 dB for 8 hours per day must wear protection. Noise above this level is considered hazardous and additional protections are recommended.

Outside of occupational settings, noise-induced hearing loss is difficult to prevent since dangerous decibel levels are present at many common everyday activities. Using properly-rated noise-blocking earplugs helps reduce unnecessary harm during loud events and environments. Over time, those small periods of protection can make a big difference in preserving long-term hearing health.

Calmer (HearSafe) Earplug Noise Reduction Rating

The Noise Reduction Rating (NRR) is a standard that gauges the capability of hearing protection devices like earplugs to cut down noise exposure, measured in decibels (dB). The rule of thumb is straightforward: the higher the NRR, the more significant the noise attenuation.

Our Calmer earplugs, crafted with the HearSafe technology, boast an actual real-world NRR of 29 dB. That means they're designed to reliably lessen noise by 29 dB in everyday environments, not just under optimal lab conditions. If you're in an area with a noise level of 100 dB, utilizing the Calmer earplugs should reduce this to a more manageable 71 dB (100 dB - 29 dB = 71 dB).

Unlike many other earplugs where the laboratory NRR may overstate the performance you can expect in the field, HearSafe earplugs ensure the promised 29 dB noise reduction carries over into the real-world. This level of reduction is significant, as it provides a substantial shield against the potential harm of loud noises.

The distinction here is that HearSafe earplugs maintain their NRR value outside the laboratory, setting a new standard for hearing protection. You can trust that the stated NRR of 29 dB is not just a theoretical figure but a realistic reflection of the protection you'll receive.

This commitment to real-world noise reduction performance makes the HearSafe Calmer earplugs a leading choice for anyone seeking reliable, high-quality ear protection. Whatever the noisy scenario, Calmer earplugs are adept at reducing sound to safer levels, preserving your hearing without compromise.

Continuous Noise Blocking

Continuous noise consists of stable, ongoing sounds that persist over time, such as the low hum of appliances, fans, and air conditioning units. This form of auditory disturbance often becomes a subliminal stressor that can contribute to mental exhaustion and disrupt restful sleep.

Our Calmer earplugs, endowed with HearSafe technology, are adept at mitigating continuous noise exposures with their true-to-life noise reduction rating (NRR) of 29 decibels.
