Introduction: Soundproof earplugs rely on passive noise reduction. If you require active noise cancellation, please choose active noise-canceling headphones.

However, ASMR alone is often not enough; we also need a quiet and comfortable environment to fall asleep. Various kinds of noise are always unexpectedly encountered, especially in dormitories and similar settings, making it hard to avoid. Soundproof earplugs for sleep are a great choice. However, with the myriad of sleep earplugs available, it can be quite difficult for the average consumer to make the best choice.

As the name suggests, sleep soundproof earplugs are primarily intended for sleep. This is especially true for students living in dormitories, where snoring can sometimes be unbearable.

Based on pitch, snoring can be divided into two types:

High-pitched wheezes (sibilant wheezes): Also known as whistling sounds. These have a high pitch with a fundamental frequency reaching above 500Hz, resembling a short, blowing sound or having a musical quality. They rise in pitch during forced exhalation and often originate from smaller bronchi or bronchioles.
Low-pitched wheezes (sonorous wheezes): Also known as rhonchus rales. These have a low pitch with a fundamental frequency around 100–200Hz, resembling moaning or snoring sounds, and typically occur in the trachea or main bronchi.

From the above explanation, we can see that snoring is essentially noise above 100Hz. In daily life, we rarely hear low-frequency noise below 100Hz, and this type of noise is hard to completely filter through earplugs. Thus, the soundproofing effect of earplugs below 100Hz doesn’t differ much.

Therefore, we prioritize the noise reduction capability above 100Hz. The parameters for BET SLUMBUR SLEEP Earplugs are SNR: 32 dB (NRR: 19.1 dB). For noise in the 100Hz~500Hz range, the average noise reduction is about 28dB~32dB, and for noise above 500Hz, the average noise reduction is above 32dB.

Earplugs with good soundproofing performance are usually not comfortable, and those that are comfortable usually do not have good soundproofing performance. For earplugs, comfort is key. This is why BET SLUMBUR offers four sizes of earplugs, allowing users to choose the size that best fits their ears. This ensures optimal comfort and provides the ultimate noise reduction experience. Additionally, BET SLUMBUR earplugs can quickly balance ear pressure in just 15 seconds, making side sleeping stress-free.
