After putting on a few music audition discs, the response was not as good as before, after all, the pictures of the seascape and the natural sound of the previous ones have raised everyone's appetite, and now there are dozens of songs with different styles on the records left by Yellowstone.

For example, Guo Feng's electronic synthesizer version of "Snowflakes Flying", "Audition Equation" with female voices, "Shania-Fuain" with female voices, "Ferry" by Cai Qin, "2001: A Space Odyssey" with symphony, "Ode to Joy" with female voices, "Backgammon" by Guzheng and "Midnight Dream" by electric guitar and so on.

According to the feeling of Huangshi, not only each of these pieces of music is full of characteristics, some are like mountains and flowing water, lingering sounds, some are imminent, ethereal, some are breezy and bright, the sound of nature, and some are reverberating and deafening.

It's a pity that everyone doesn't know the goods, and they waste the kindness of Huangshi, in addition to thinking that the melody of the music is more beautiful, the lyrics of those official words can still be half understood, but like the lyrics of those fans, even Chen Youxin, who often does business in Fanbang, can't understand it, so Hong'er made a brief introduction before this ending, "Mr. Zhang asked what is 'middle and high pitch' and 'heavy bass', and we listened to these songs, like the ...... in these songs."

In this way, Hong'er explained Huang Shi's previous comments on the vocal range and timbre of the songs in these audition discs to everyone present.

In the human frequency range, ultra-bass refers to less than 40 Hz, bass is less than 500 Hz, midrange is 500 Hz to 8 thousand Hz, and treble is above 8 thousand Hz.

However, in digital signals, it is difficult to see subwoofer, because the digital signal is distorted, which is suitable for relatively dull instrument sounds, and is not suitable for reproducing complex vocals. The analog signal of the cassette tape can be as low as 15 to 20 Hz, and the bass part of the sound quality is very full.

Therefore, Huang Shi said about the timbre of those music, like soprano, that is, the timbre in the high register is bright, mellow, and relaxed, and the strength and strength in the middle and low registers are weak. The mezzo-soprano is the timbre of the entire midrange area is bright, full, rich and round, the treble is not very casual, and the timbre is slightly dark. As for the contralto, it is in the mid-bass range, with a rich, strong and powerful tone. The treble is weaker and darker, etc.

Whereas, the tenor is a bright and pure timbre in the mid-upper register, with penetrating power, and a slightly weaker bass. The baritone is full-bodied, sturdy, and masculine. As for the bass, the timbre is deep, thick, wide and powerful. For example, Zhu Zhiwen, a peasant singer who has become famous on CCTV recently, is a bass, and his song "Linjiang Immortal" is not much better than the original singer Yang Hongji.

It's a pity that under the aura of the first two, music, an auditory art that can go straight to the human heart, did not make everyone's hearts resonate with music, nor did they let their hearts bathe in the river of music, let alone sublimate their lives to another realm, they just nodded lightly and responded with an "oh".

If Huangshi was here, he would definitely think that he was "playing the piano to the cow", but Hong'er was not surprised, because she was also a person without musical cells, and when she saw that everyone had seen the charm of TV and stereo, she immediately turned around and introduced other electrical appliances in the living room.

……

The living room is used as a place for most families to rest, entertain and meet guests, so it is the top priority of the whole house home design, especially when there are guests coming, the first thing you will see is the living room, this first impression is very important, the owner's taste of life can be reflected in the living room layout, if you want to add a little impression to yourself, then the living room layout must not be sloppy.

Therefore, in addition to sofas, bookshelves and other furniture in the living room, household appliances are also an important part of the style design of the living room, flat-screen TV and vertical air conditioning are essential, so put the refrigerator in the kitchen, or the living room, can also reflect the living habits of the owner of the room.

Due to the small area of the model room, coupled with the fact that Huangshi bought a refrigerator with a fragrant red colored crystal glass panel, not only the color of the refrigerator panel is fashionable and bright, but also it uses dark red lines to outline the traditional Chinese element peony, and the handle is also a hidden form of the handle, from the appearance it does not look like an electrical appliance, more like an elegant handicraft placed in the corner of the living room.

Like it, there are three pieces of "handicrafts", which are also resting in other corners of the living room, the largest of which is a vertical air conditioner, because it is very necessary to have a large area of the living room, and the strong cooling and heating of the vertical air conditioner can ensure the right room temperature.

Like the "peony-patterned" refrigerator, this air conditioner can open the front door to facilitate cleaning of the air conditioner's filter and other internal equipment. At the same time, its exterior design is also excellent, and the overall golden appearance with lotus decoration makes it even more rich and extraordinary.

A small "handicraft" is a water dispenser, because it is not possible to receive guests without tea, so it is much more convenient to place a water dispenser in the living room. However, the current water dispenser is no longer as simple as it was back then, not so much a water dispenser, but more like a small, streamlined, milky white refrigerator, the appearance is also simple and generous, and the white panel is also depicted with floral patterns.

It is also a double-door design, with a black interface indicator at the upper end of the body to indicate the current working status, and an automatic high-brightness night water intake lamp, which is convenient for users to use at night. The door is opened to the original hot and cold water intake, and the lower door is a large-capacity fresh-keeping cabinet, which can put some tea sets and tea leaves, etc., which is safer to sterilize and keep fresh.

There is also a small "handicraft", that is, an air purifier, but this small household appliance Huangshi has not been used back then, because Fuzhou's air quality is above high quality all year round, and it ranks 939th in the ranking of PM10 concentrations in 1100 cities around the world, and it ranks 5th in the country, so Lao Huang can't use it at all. However, many of his colleagues in Beijing, Shanghai and Guangzhou are deeply affected by PM10, especially since this year, in addition to wearing masks when going out, they also have to equip this small thing at home.

Yellowstone didn't want to buy it originally, because the air was fresh in Dongluo Island in the 16th century, even fresher than Canada in the 21st century, because there was no trace of industry at all. However, he also heard from the salesperson that this air purifier can not only keep the living room fresh air at all times and ensure the health of the home environment, but also effectively purify the indoor dust and air, and at the same time remove formaldehyde with a higher effect.

So Huang Shi thought, he has just finished the decoration of that model house, and used a lot of gold steel plate and wallpaper in the decoration, I heard that in addition to the gold steel plate and wallpaper itself will emit formaldehyde, the strong glue and glue used to bond them will exceed the formaldehyde standard, usually more than 10 times the national standard.

Therefore, as soon as he heard the salesman say this, he looked at the air purifier, its appearance design is refreshing and concise, using a green and white clay pot, and the panel is embellished with green flowers, giving people a feeling of being close to nature, and at the same time, the small body makes it not take up extra home space.

After he bought it back, this air purifier occupied the last corner of the living room, and stood on top of the air conditioner, refrigerator, and water dispenser. I don't know if it is his psychological factor or if there is indeed excessive formaldehyde in the room, after opening this equipment, he feels that the air is much fresher and more comfortable, and compared with the air conditioner, it is not so dry.

……

Hong'er led everyone to turn around the four corners of the hall and introduced the refrigerator, air conditioner, water dispenser, and air purifier.

"Refrigerator", everyone present has actually seen it, the earliest two were placed in An Ruyi's warehouse, both of which were ordinary double-door refrigerators, at first everyone did not know what it was used for, and later after the diesel generators on the island were activated, they and those freezers were moved to the kitchen for use.

Keeping food at a lower temperature is less susceptible to spoilage, which has been a well-known phenomenon since ancient times. Therefore, in the Book of Songs, it is recorded that ice cubes are chiseled in the twelfth month of the summer calendar, and ice cubes are hidden in the ice cellar in the first month. There is also a record of "Bingjian" in "Zhou Li".

According to research, the so-called "ice jian" is a container used to hold ice and put food in it in the summer. Counting, "Bingjian" should be the earliest "refrigerator" used by human beings. "Wu Yue Spring and Autumn" also recorded: "Gou Jianzhi travels, rests and lodging in the ice kitchen." The "ice kitchen" mentioned here is the place where the emperor prepares food and drink in the summer, so it is also called the "cold palace". The "cold palace" has the functions of a modern refrigerator and air conditioner.

Moreover, the ancients also applied the "refrigerator" technology to production and transportation. Huang Province of the Ming Dynasty once wrote in the "Book of Fish" that fishermen often "raised white-scaled fish with ice" and transported it to distant places, which was called "chilled". From this point of view, the storage method of "raising it with ice" was already very common in the Ming Dynasty at the latest.

At the same time, the ancient Tibetan ice was said to be used to worship the gods, and it was said to be used to prepare for the summer day, and it was also equipped with a special official who managed the ice storehouse, and the name was "Ling Ren". Every winter, the ice in the river is chiseled into large chunks, put in cellars, and then sealed to prevent air from entering, and this ice can be preserved until the hot summer.

In the Forbidden City of the Qing Dynasty, there were 5 ice cellars, and nearly 30,000 pieces of ice were used to store ice or perishable items in summer, and their functions were similar to today's "refrigerators", and this method was used until the late Qing Dynasty.

At the beginning, the Jiang family was a large family within a radius of more than ten miles, and naturally there was an "ice cellar" in the village, and the ice cubes were intercepted from the river every winter and stored in it, and when it came to summer, the lord and his wife could drink a cup of "iced sour plum soup" to quench their thirst, of course, the people did not have a share.
