Is there any better mobile phone or computer software that measures pitch and displays hertz and decibels?
There are two main software that can measure sound frequency: Gstrings and GOLDWAVE5.7 version of the sound measurement software.
Sound frequency: The number of times an object vibrates per second is called frequency. The frequency range of the sound wave vibration that causes the sound sensation is 20~20000Hz, which is called... The expression of frequency is: f=1/T where: f- is the frequency (Hz) T- is the time to complete a vibration cycle ( sec) The frequency and intensity of sound are the most important physical parameters that affect the effect of sound on the human body.
The treble frequency range of a child's voice is 260-880Hz, the bass frequency range is 196-700Hz, the treble frequency range of a female voice is 220-1.1KHz, the bass frequency range is 200-700KHz, and the treble frequency range of a male voice is 160-523KHz. 80-358Hz.
What software is available to detect the noise level around you?
1. Test noise decibel app: Test noise decibel app is a mobile phone software that supports online noise testing. It occupies small memory, is simple to operate, has powerful functions, has high accuracy of test results and is highly praised.
2. Noise detector app: It is used to detect the noise pollution index around you.
3. Noise detection app: It is a mobile phone application used to measure noise. It is small and practical, and the test results are accurate! Frequent noise measurement can effectively prevent noise damage and protect the health of your family.
Noise testing apps are divided into many forms, including environmental noise detection apps and low-frequency noise detection apps, among which environmental noise detection apps are the most commonly used. Because there will be a lot of noise in life, and in order to protect the healthy living environment of the people, there will be relevant noise regulations in various places. In China, the noise should not exceed 30 decibels at night (22:00 to 6:00 the next day), and during the day ( 6:00 to 22:00) shall not exceed 40 decibels. These recommended noise detection instruments can detect noise very accurately and are also very convenient to operate. The decibel noise test provides users with professional noise detection, which can be downloaded and used if necessary.
Extended information:
The standard for the environment noise is a stipulation on the allowable range of noise in order to protect people's health and living environment. The formulation of principles should be based on protecting people's hearing, sleep, rest, conversation and thinking, and should be advanced, scientific and realistic. The basic environmental noise standards are the basic basis for environmental noise standards. Most countries refer to the base numbers recommended by the International Organization for Standardization (ISO) (for example, 30 decibels for sleep) and formulate their own standards based on their own national and local conditions.
Including outdoor noise standards in different regions and indoor noise standards with different usage requirements, it is a type of environmental standard. The purpose of formulating such standards is to control the impact of noise on people and provide a basis for the rational adoption of noise control technologies and the implementation of noise control legislation.
Strong noise can have adverse effects on human physiology and psychology. In daily work and living environments, noise mainly causes hearing loss and interferes with talking, thinking, rest and sleep. According to a survey by the International Organization for Standardization (ISO), after working in an environment with noise levels of 85 decibels and 90 decibels for 30 years, the likelihood of deafness is 8% and 18% respectively. Conversation becomes difficult in an environment with a noise level of 70 decibels. A survey of residents around the factory concluded that the noise level threshold that interferes with sleep and rest is 50 decibels during the day and 45 decibels at night.
Is there any software to test the decibel volume of computer headphones?
Detection software: sound meter 2.0 (sound detector)
Software introduction: sound meter 2.0 (sound detector) integrates two detection instruments - sound and oscillation. Sound detectors use your device's microphone to measure decibels of noise, while vibration detectors use your device's sensors to measure vibrations and earthquakes.
Detection method: Install sound meter 2.0 on the Android phone, open sound meter 2.0 (sound detector) on the phone, and place the microphone of the phone close to the computer headset , which can detect the decibel level of the headphone volume.
Health advice: Do not use headphones to listen to music or high-decibel music for a long time. Frequent use of in-ear headphones to listen to music can lead to hearing loss. The commonly used in-ear headphones now achieve good music effects by inserting the sound outlet into the inner ear. The sound emitted directly stimulates the auditory cells through the inner ear. In the long run, the auditory cells will be damaged due to insufficient blood supply and oxygen supply, leading to hearing loss. , and more seriously, it can lead to deafness. Therefore, you should try to use headphones as little as possible, especially in-ear headphones, and try not to turn the music volume too high.
Which noise detector is the best? Look here!
There are many noise detectors, among which Test Noise Decibel App v5.2.0 Android version, Noise Detector Mobile Version v16.10.25 Android Version, Noise Detector v5.2.61 Android Version, Noise Identifier Mobile Version v1.1.0 Android Version, You Noise (noise measurement) v1.1.0 Android version , etc. These are all very good software.
1. Test noise decibel app v5.2.0 Android version
Test Noise Decibel App is a mobile phone software that supports online noise testing. It occupies small memory, is simple to operate, has powerful functions, and has high accuracy of test results. It achieves real-time and intuitive quantification of noise. You can use this noise tester. It can be used for noise testing and recording in public places such as study, accommodation, work, squares, etc.
2. Noise detector mobile version v16.10.25 Android version
The Noise Detector app is used to detect the noise pollution index around you. As we all know, too much sound pollution has a serious impact on the human body. This software uses the mobile phone microphone to measure environmental noise and decibel (dB) size. Test A numerical value will be displayed for reference.
3. Noise Detection v5.2.61 Android version
The noise detection app is a software that uses the mobile phone microphone to measure environmental noise and decibel (dB) size. After the test, a value will be displayed for reference. Through this small tool, you can easily measure the noise level of the current environment. It is simple to operate and easy to use. When the decibel value of the surrounding environment is too high, it will cause harm to people's psychology and physiology, and the noise will also damage the hearing function. .
4. Noise Identifier Mobile Version v1.1.0 Android Version
The Noise Identifier app is a very interesting but powerful mobile phone utility. For the sounds around you, the Noise Identifier app can record and detect the noise information index in real time, and easily understand the surrounding environment. If it is not suitable for life, leave as soon as possible. , the interface is fresh and high-quality, and it is very convenient to use.
