How to tell whether the sound is good or bad? A guide to teach you how to choose high-quality speakers
In today's era of rapid technological development, audio equipment has become an indispensable part of our lives. Whether it is home theater, music appreciation or game entertainment, a high-quality speaker can bring the ultimate listening experience. However, facing the dazzling array of audio products on the market, how to distinguish the quality of the audio has become a problem for many consumers. This article will combine the hot topics and hot content on the Internet in the past 10 days to analyze how to choose high-quality speakers from multiple dimensions.
1. Analysis of core parameters of audio
To distinguish the quality of speakers, you first need to understand several key parameters. The following are the main technical indicators that affect the sound quality of speakers:
| Parameter name | importance | ideal range | illustrate |
|---|---|---|---|
| Frequency response range | ★★★★★ | 20Hz-20kHz | Covers the audible range of the human ear, the wider the value, the better |
| signal-to-noise ratio | ★★★★☆ | ≥90dB | The higher the value, the smaller the background noise |
| total harmonic distortion | ★★★★☆ | <0.1% | The lower the value, the purer the sound quality |
| Sensitivity | ★★★☆☆ | 85-90dB | Higher values make it easier to drive |
| Rated power | ★★★☆☆ | Depends on usage environment | Match the space used |
2. Subjective evaluation method of audio quality
In addition to objective parameters, the sound quality of speakers also needs to be judged through subjective listening. The following are several key evaluation dimensions:
1.Analytical power: Excellent speakers can clearly restore every detail in the music, including the overtones of instruments, the singer's breathing and other subtle sounds.
2.Sound field performance: High-quality audio can create a wide, three-dimensional sound field, allowing the listener to feel the positioning and space of the instrument.
3.Three-band equalization: Good speakers should have balanced performance in high, medium and low frequency bands, and no certain frequency band will be too prominent or missing.
4.dynamic range: Able to clearly express the transition from the pianissimo to the strongest sound without distortion or compression.
5.sound density: The sound is full and textured, not thin or hollow.
3. Key points for purchasing different types of speakers
According to different usage scenarios and needs, speakers can be divided into the following categories, each with its own purchase points:
| Speaker type | Applicable scenarios | Key points for purchasing | Represent the brand |
|---|---|---|---|
| bookshelf speakers | Small room, near field listening | Focus on mid- and high-frequency performance and analytical power | KEF, B&W, Dynaudio |
| floor standing speakers | living room, large space | Pay attention to low-frequency extension and dynamic range | JBL, Bowers & Wilkins, Tannoy |
| Soundbar | TV sound, simplified system | Favorite virtual surround effect and connection convenience | Sony, Samsung, Bose |
| bluetooth speaker | Portable use | Pay attention to battery life, waterproof performance, and balanced sound quality | JBL, B&O, Marshall |
| monitor speakers | Professional recording and music production | Pursuing accurate restoration and flat frequency response | Genelec, Adam, Yamaha |
4. Recent hot audio technology trends
According to the hot discussions on the Internet in the past 10 days, the following audio technology trends are worthy of attention:
1.spatial audio technology: The spatial audio technology launched by Apple, Sony and other brands can create a more realistic 3D sound experience.
2.AI sound quality optimization: More and more audio products use AI algorithms to automatically optimize sound quality and adapt to different environments and music types.
3.High-resolution audio support: Supporting high-resolution audio playback of 24bit/192kHz and above specifications has become a standard feature of high-end audio.
4.Wireless transmission technology upgrade: New wireless standards such as Wi-Fi 6 and Bluetooth 5.3 have significantly improved the sound quality stability of wireless speakers.
5.Environmentally friendly materials application: The concept of sustainable development and environmental protection drives audio manufacturers to use more recyclable materials.
5. Practical suggestions for purchasing speakers
1. Determine the budget range and avoid blindly pursuing high-priced products.
2. Try to listen to it on site, or choose products that support no-reason returns on e-commerce platforms.
3. Consider the possibility of future upgrades and choose a system that supports modular expansion.
4. Pay attention to after-sales service, especially the warranty policy of high-end audio.
5. Pay attention to the compatibility of the audio with existing equipment, such as power amplifier matching, interface type, etc.
Through the analysis of the above five aspects, I believe you have mastered the basic method of distinguishing the quality of sound. Remember, the best speaker is not necessarily the most expensive one, but the one that best suits your needs and listening preferences. I hope this guide will help you find a truly satisfactory choice among the many audio products.
