Sleep is our biological necessity, and disturbed sleep is associated with a number of health issues. Noise is one of the biggest culprits of disturbed sleep. Noise disturbs sleep by a number of direct and indirect ways. Even at very low levels physiological reactions (increase in heart rate, body movements and arousal) can be reliably measured. For tips on improving sleep quality in noisy environments, read How to Improve Sleep Quality in Noisy Environments. See the chart below for more on how average night noise levels outside impact our overall health and well-being:

Average night noise level over a year Lnight, outside	Health effects observed in the population
Up to 30 dB	Although individual sensitivities and circumstances may differ, it appears that up to this level, no substantial biological effects are observed. Lnight,outside of 30 dB is equivalent to the no observed effect level (NOEL) for night noise.
30 to 40 dB	A number of effects on sleep are observed from this range: body movements, awakening, self-reported sleep disturbance, arousal. The intensity of the effect depends on the nature of the source and the number of events. Vulnerable groups (for example children, the chronically ill and the elderly) are more susceptible. However, even in the worst cases the effects seem modest. Lnight,outside of 40 dB is equivalent to the lowest observed adverse effect level (LOAEL) for night noise.
40 to 55 dB	Adverse health effects are observed among the exposed population. Many people have to adapt their lives to cope with the noise at night. Vulnerable groups are more severely affected.
Above 55 dB	The situation is considered increasingly dangerous for public health. Adverse health effects occur frequently, a sizeable proportion of the population is highly annoyed and sleep-disturbed. There is evidence that the risk of cardiovascular disease increases

  Increasing urban noise is considered increasingly dangerous for public health. Adverse health effects occur frequently, a sizeable proportion of the population is highly annoyed and sleep disturbed. There is evidence that the risk of cardiovascular disease is increasing. As night-time environmental noise affects people mainly inside their homes. In order to protect people inside their homes from noise from outside sources, attention should be focused on windows since they are generally the weakest points in the sound propagation path. Roofs must also be considered with regard to aircraft noise. The structure of the building also has an impact on the noise level inside the building. The simplest types of facade have a sound reduction (from outside to inside) of usually less than 24 dB, and the most elaborate facades (built to cope with cold climates, for example), have sound reductions of more than 45 dB. In north america, most windows are double-glazed, mounted in a rigid and well-insulated frame. Their range of sound reduction is between 30 dB and 35 dB when closed. However, many people like to sleep with open windows to get fresh air and thus increasing indoor noise levels. For those struggling with noise during sleep, products like the QuietOn 3.1 Sleep Earbuds or Ozlo Sleepbuds can provide effective solutions.

How do I choose the right attenuation level of my sleep plug

Choosing the right attenuation level for your needs depends on several factors, including the environment you’ll be in and your personal comfort preferences. Here are some tips to help you decide:

1. Identify Your Noise Environment

• Quiet Environments: If you’re in a relatively quiet environment and just need to block out minor disturbances, a lower attenuation level (15-20 dB) might be sufficient.
• Moderate Noise: For environments with moderate noise, such as a busy street nearby or urban area, look for earplugs with an attenuation level of 20-30 dB.
• High Noise Levels: In very noisy environments, like faulty elevator, snoring partner. Loud neighbours or while traveling, higher attenuation levels (28-33 dB) are recommended.

2. Consider Your Sensitivity to Noise

• High Sensitivity: If you’re particularly sensitive to noise, opt for earplugs with higher attenuation levels to ensure maximum noise reduction.
• Moderate Sensitivity: If you can tolerate some background noise, medium attenuation levels might be more comfortable and still effective.

3. Your hearing health

• Hearing loss- If you have an existing hearing loss then please consult your healthcare professional for the right level of attenuation. If you never got a hearing test. Use the HearfIT online hearing screener

4. Comfort and Fit

• Long-Term Wear: If you need to wear earplugs for extended periods, consider the comfort and fit. Digital earplugs are generally more comfortable for long-term multi environment use.
• Reusable Options: If you prefer reusable options, silicone, digital or filtered earplugs might be more suitable.

5. Budget

• Cost-Effective: Foam earplugs are the most affordable option and provide high attenuation if they seal your ears perfectly.
• Investment: Digital earplugs are more expensive but they last much longer, they offer advanced features like active noise cancellation and customizable settings.

6. Trial and Error

• Experiment: Sometimes, the best way to find the right earplugs is to try a few different types and see which ones work best for you in various situations.

By considering these factors, you can choose the right attenuation level and type of earplugs that best meet your needs. According to Sharad Ojha, the founder of HearFIT, the most common myth about sleep plugs is that a good sleep plug will block all noises. This is far from being true. “A good sleep plug is highly effective at partially reducing noise. They will not block out all sounds entirely. They are designed to lower the volume of disruptive noises to a level that is less likely to wake you up. This includes noises like snoring, traffic, or household sounds. Hearing some sound is important for your safety.” Sharad managed audiology clinics for years and when it came to the sleep plugs the most common question he got asked.

As What to Expect from a Good Sleep Plug

1. Noise Reduction:

   • Effective Attenuation and not complete silence: A good sleep plug should significantly reduce ambient noise, helping to create a quieter environment conducive to sleep. However, it’s important to note that no earplug can block out all sounds completely. They are designed to attenuate noise to a level that will help you sleep peacefully.

2. Comfort:

   • Soft and Moldable: Look for earplugs made from materials like foam or silicone that can conform to the shape of your ear canal. This ensures a snug fit without causing discomfort, even when worn for extended periods.

3. Fit and Seal:

   • Proper Fit: A good sleep plug should fit well in your ear canal, creating an effective seal. This helps in maximizing noise reduction and preventing the earplugs from falling out during sleep.

4. Hygiene:

   • Clean and Safe: Choose earplugs that are easy to clean or disposable after a few uses to maintain ear hygiene and prevent infections. When using digital ear plugs, change the eartips every 2-3 months

5. Durability:

   • Reusable Options: If you prefer reusable earplugs, ensure they are durable and can withstand regular cleaning without degrading in performance.

Will It Block All Sounds?

• Partial Noise Blocking: While sleep plugs are highly effective at reducing noise, they will not block out all sounds entirely. They are designed to lower the volume of disruptive noises to a level that is less likely to wake you up. This includes noises like snoring, traffic, or household sounds.
• Selective Hearing: Some earplugs, especially filtered ones, are designed to allow certain important sounds, like alarms or emergency signals, to be heard while blocking out background noise.

Tips for Maximizing Effectiveness

• Correct Insertion: Ensure you insert the earplugs correctly to achieve the best seal and noise reduction.
• Combination with White Noise: Using earplugs in combination with a white noise machine can further enhance your sleep environment by masking residual sounds.

In summary, a good sleep plug will significantly reduce noise levels, improve your sleep quality, and provide comfort throughout the night. However, they will not eliminate all sounds completely. If you have any specific concerns or need personalized advice, it’s always best to consult with a healthcare professional.
